+# Migrate from Symantec to Microsoft Defender Advanced Threat Protection
+
+If you are planning to switch from Symantec Endpoint Protection (Symantec) to [Microsoft Defender Advanced Threat Protection](https://docs.microsoft.com/windows/security/threat-protection) (Microsoft Defender ATP), you're in the right place. Use this article as a guide to plan your migration.  
+
+## The migration process
+
+When you switch from Symantec to Microsoft Defender ATP, you follow a process that can be divided into three phases, as depicted in the following image:
+
+:::image type="content" source="images/SymantecMigration-DefenderATP-overview.png" alt-text="Phase 1 - Prepare. Phase 2 - Setup. Phase 3 - Onboard":::
+
+- During the [**Prepare** phase](symantec-to-microsoft-defender-atp-prepare.md), you get Microsoft Defender ATP, plan your roles and permissions, and grant access to the Microsoft Defender Security Center. You also configure your device proxy and internet settings to enable communication between your organization's devices and Microsoft Defender ATP.
+
+- During the [**Setup** phase](symantec-to-microsoft-defender-atp-setup.md), you configure settings and exclusions for Microsoft Defender Antivirus, Microsoft Defender ATP, and Symantec Endpoint Protection. You also create device groups, collections, and organizational units. Finally, you configure your antimalware policies and real-time protection settings.
+
+- During the [**Onboard** phase](symantec-to-microsoft-defender-atp-onboard.md), you onboard your devices to Microsoft Defender ATP and verify that those devices are communicating with Microsoft Defender ATP. Last, you uninstall Symantec and make sure protection through Microsoft Defender ATP is in place.
+
+## What's included in Microsoft Defender ATP?
+
+In this migration guide, we focus on [next-generation protection](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-antivirus/microsoft-defender-antivirus-in-windows-10) and [endpoint detection and response](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/overview-endpoint-detection-response) capabilities as a starting point for moving to Microsoft Defender ATP. However, Microsoft Defender ATP includes much more than antivirus and endpoint protection. Microsoft Defender ATP is a unified platform for preventative protection, post-breach detection, automated investigation, and response. The following table summarizes features and capabilities in Microsoft Defender ATP. 
+
+| Feature/Capability | Description |
+|---|---|
+| [Threat & Vulnerability Management](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/next-gen-threat-and-vuln-mgt) | Threat & Vulnerability Management capabilities helps identify, assess, and remediate weaknesses across your endpoints (such as devices). |
+| [Attack surface reduction](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/overview-attack-surface-reduction) | Attack surface reduction rules help protect your organization's devices and applications from cyberthreats and attacks. |
+| [Next-generation protection](https://docs.microsoft.com/windows/security/threat-protection/windows-defender-antivirus/windows-defender-antivirus-in-windows-10) | Next-generation protection includes Microsoft Defender Antivirus to help block threats and malware. |
+| [Endpoint detection and response](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/overview-endpoint-detection-response) | Endpoint detection and response capabilities detect, investigate, and respond to intrusion attempts and active breaches.  |
+| [Advanced hunting](advanced-hunting-overview.md) | Advanced hunting capabilities enable your security operations team to locate indicators and entities of known or potential threats. |
+| [Behavioral blocking and containment](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/behavioral-blocking-containment) | Behavioral blocking and containment capabilities help identify and stop threats, based on their behaviors and process trees even when the threat has started execution. |
+| [Automated investigation and remediation](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/automated-investigations) | Automated investigation and response capabilities examine alerts and take immediate remediation action to resolve breaches. |
+| [Threat hunting service](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/microsoft-threat-experts) (Microsoft Threat Experts) | Threat hunting services provide security operations teams with expert level monitoring and analysis, and to help ensure that critical threats aren't missed. |

+This migration phase includes the following steps:
+1. [Get Microsoft Defender ATP](#get-microsoft-defender-atp).
+2. [Grant access to the Microsoft Defender Security Center](#grant-access-to-the-microsoft-defender-security-center).
+3. [Configure device proxy and internet connectivity settings](#configure-device-proxy-and-internet-connectivity-settings).
+
+## Get Microsoft Defender ATP
+
+To get started, you must have Microsoft Defender ATP, with licenses assigned and provisioned.
+
+1. Buy or try Microsoft Defender ATP today. [Visit Microsoft Defender ATP to start a free trial or request a quote](https://aka.ms/mdatp). 
+
+2. Verify that your licenses are properly provisioned. [Check your license state](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/production-deployment#check-license-state).
+
+3. As a global administrator or security administrator, set up your dedicated cloud instance of Microsoft Defender ATP. See [Microsoft Defender ATP setup: Tenant configuration](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/production-deployment#tenant-configuration).
+
+4. If endpoints (such as devices) in your organization use a proxy to access the internet, see [Microsoft Defender ATP setup: Network configuration](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/production-deployment#network-configuration).
+ 
+At this point, you are ready to grant access to your security administrators and security operators who will use the Microsoft Defender Security Center ([https://aka.ms/MDATPportal](https://aka.ms/MDATPportal)). 
+
+> [!NOTE]
+> The Microsoft Defender Security Center is sometimes referred to as the Microsoft Defender ATP portal. 
+
+## Grant access to the Microsoft Defender Security Center
+
+The Microsoft Defender Security Center ([https://aka.ms/MDATPportal](https://aka.ms/MDATPportal)) is where you access and configure features and capabilities of Microsoft Defender ATP. To learn more, see [Overview of the Microsoft Defender Security Center](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/use).
+
+Permissions to the Microsoft Defender Security Center can be granted by using either basic permissions or role-based access control (RBAC). We recommend using RBAC so that you have more granular control over permissions.
+
+1. Plan the roles and permissions for your security administrators and security operators. See [Role-based access control](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/prepare-deployment#role-based-access-control).
+
+2. Set up and configure RBAC. We recommend using [Intune](https://docs.microsoft.com/mem/intune/fundamentals/what-is-intune) to configure RBAC, especially if your organization is using a combination of Windows 10, macOS, iOS, and Android devices. See [setting up RBAC using Intune](https://docs.microsoft.com/mem/intune/fundamentals/role-based-access-control).
+
+    If your organization requires a method other than Intune, choose one of the following options:
+    - [Configuration Manager](https://docs.microsoft.com/mem/configmgr/core/servers/deploy/configure/configure-role-based-administration)
+    - [Advanced Group Policy Management](https://docs.microsoft.com/microsoft-desktop-optimization-pack/agpm)
+    - [Windows Admin Center](https://docs.microsoft.com/windows-server/manage/windows-admin-center/overview)
+
+3. Grant access to the Microsoft Defender Security Center. (Need help? See [Manage portal access using RBAC](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/rbac)).
+
+## Configure device proxy and internet connectivity settings
+
+To enable communication between your devices and Microsoft Defender ATP, configure proxy and internet settings. The following table includes links to resources you can use to configure your proxy and internet settings for various operating systems and capabilities:

+# Migrate from Symantec - Phase 2: Set up Microsoft Defender ATP
+
+:::image type="content" source="images/SymantecMigration-DefenderATP-phase2.png" alt-text="Phase 2 - Setup":::
+
+**Welcome to the Setup phase of [migrating from Symantec to Microsoft Defender ATP](symantec-to-microsoft-defender-atp-migration.md#the-migration-process)**. This phase includes the following steps:
+1. [Enable or reinstall Microsoft Defender Antivirus (for certain versions of Windows)](#enable-or-reinstall-microsoft-defender-antivirus-for-certain-versions-of-windows).
+2. [Enable Microsoft Defender Antivirus](#enable-microsoft-defender-antivirus).
+3. [Add Microsoft Defender ATP to the exclusion list for Symantec](#add-microsoft-defender-atp-to-the-exclusion-list-for-symantec).
+4. [Add Symantec to the exclusion list for Microsoft Defender Antivirus](#add-symantec-to-the-exclusion-list-for-microsoft-defender-antivirus).
+5. [Add Symantec to the exclusion list for Microsoft Defender ATP](#add-symantec-to-the-exclusion-list-for-microsoft-defender-atp).
+6. [Set up your device groups, device collections, and organizational units](#set-up-your-device-groups-device-collections-and-organizational-units).
+7. [Configure antimalware policies and real-time protection](#configure-antimalware-policies-and-real-time-protection).
+
+## Enable or reinstall Microsoft Defender Antivirus (for certain versions of Windows)
+
+> [!TIP]
+> If you're running Windows 10, you do not need to perform this task. Proceed to **[Enable Microsoft Defender Antivirus](#enable-microsoft-defender-antivirus)**.
+
+On certain versions of Windows, Microsoft Defender Antivirus might have been uninstalled or disabled. This is because Microsoft Defender Antivirus does not enter passive or disabled mode when you install a third-party antivirus product, such as Symantec. To learn more, see [Microsoft Defender Antivirus compatibility](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-antivirus/microsoft-defender-antivirus-compatibility). 
+
+Now that you're moving from Symantec to Microsoft Defender ATP, you'll need to enable or reinstall Microsoft Defender Antivirus, and set it to passive mode. 
+
+### Reinstall Microsoft Defender Antivirus on Windows Server
+
+> [!NOTE]
+> The following procedure applies only to endpoints or devices that are running the following versions of Windows:
+> - Windows Server 2019
+> - Windows Server, version 1803 (core-only mode)
+> - Windows Server 2016
+> 
+> Microsoft Defender Antivirus is built into Windows 10, but it might be disabled. In this case, proceed to [Enable Microsoft Defender Antivirus](#enable-microsoft-defender-antivirus).
+
+1. As a local administrator on the endpoint or device, open Windows PowerShell.
+
+2. Run the following PowerShell cmdlets: <br/>
+   `Dism /online /Get-FeatureInfo /FeatureName:Windows-Defender-Features` <br/>
+   `Dism /online /Get-FeatureInfo /FeatureName:Windows-Defender` <br/>
+
+3. To verify Microsoft Defender Antivirus is running, use the following PowerShell cmdlet: <br/>
+   `Get-Service -Name windefend`
+
+> [!TIP]
+> Need help? See [Microsoft Defender Antivirus on Windows Server 2016 and 2019](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-antivirus/microsoft-defender-antivirus-on-windows-server-2016).
+
+### Set Microsoft Defender Antivirus to passive mode on Windows Server
+
+Because your organization is still using Symantec, you must set Microsoft Defender Antivirus to passive mode. That way, Symantec and Microsoft Defender Antivirus can run side by side until you have finished onboarding to Microsoft Defender ATP.
+
+1. Open Registry Editor, and then navigate to <br/>
+   `Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Windows Advanced Threat Protection`.
+
+2. Edit (or create) a DWORD entry called **ForceDefenderPassiveMode**, and specify the following settings:
+   - Set the DWORD's value to **1**.
+   - Under **Base**, select **Hexadecimal**.
+
+> [!NOTE]
+> You can use other methods to set the registry key, such as the following:
+>- [Group Policy Preference](https://docs.microsoft.com/previous-versions/windows/it-pro/windows-server-2012-R2-and-2012/dn581922(v=ws.11))
+>- [Local Group Policy Object tool](https://docs.microsoft.com/windows/security/threat-protection/security-compliance-toolkit-10#what-is-the-local-group-policy-object-lgpo-tool)
+>- [A package in Configuration Manager](https://docs.microsoft.com/mem/configmgr/apps/deploy-use/packages-and-programs)
+
+## Enable Microsoft Defender Antivirus
+
+Because your organization has been using Symantec as your primary antivirus solution, Microsoft Defender Antivirus is most likely disabled on your organization's Windows devices. This step of the migration process involves enabling Microsoft Defender Antivirus. 
+
+To enable Microsoft Defender Antivirus, we recommend using Intune. However, you can any of the methods that are listed in the following table:
+
+|Method  |What to do  |
+|---------|---------|
+|[Intune](https://docs.microsoft.com/mem/intune/fundamentals/tutorial-walkthrough-endpoint-manager) <br/><br/>**NOTE**: Intune is now Microsoft Endpoint Manager. |1. Go to the [Microsoft Endpoint Manager admin center](https://go.microsoft.com/fwlink/?linkid=2109431) and sign in.<br/><br/>2. Select **Devices** > **Configuration profiles**, and then select the profile type you want to configure. If you haven't yet created a **Device restrictions** profile type, or if you want to create a new one, see [Configure device restriction settings in Microsoft Intune](https://docs.microsoft.com/intune/device-restrictions-configure).<br/><br/>3. Select **Properties**, and then select **Configuration settings: Edit**.<br/><br/>4. Expand **Microsoft Defender Antivirus**. <br/><br/>5. Enable **Cloud-delivered protection**.<br/><br/>6. In the **Prompt users before sample submission** dropdown, select **Send all samples automatically**.<br/><br/>7. In the **Detect potentially unwanted applications** dropdown, select **Enable** or **Audit**.<br/><br/>8. Select **Review + save**, and then choose **Save**.<br/><br/>For more information about Intune device profiles, including how to create and configure their settings, see [What are Microsoft Intune device profiles?](https://docs.microsoft.com/intune/device-profiles).|
+|Control Panel in Windows     |Follow the guidance here: [Turn on Microsoft Defender Antivirus](https://docs.microsoft.com/mem/intune/user-help/turn-on-defender-windows). <br/><br/>**NOTE**: You might see *Windows Defender Antivirus* instead of *Microsoft Defender Antivirus* in some versions of Windows.        |
+|[Advanced Group Policy Management](https://docs.microsoft.com/microsoft-desktop-optimization-pack/agpm/) <br/>or<br/>[Group Policy Management Console](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-antivirus/use-group-policy-microsoft-defender-antivirus)  |1. Go to `Computer configuration > Administrative templates > Windows components > Microsoft Defender Antivirus`. <br/><br/>2. Look for a policy called **Turn off Microsoft Defender Antivirus**.<br/> <br/>3. Choose **Edit policy setting**, and make sure that policy is disabled. This enables Microsoft Defender Antivirus. <br/><br/>**NOTE**: You might see *Windows Defender Antivirus* instead of *Microsoft Defender Antivirus* in some versions of Windows. |
+
+### Verify that Microsoft Defender Antivirus is in passive mode
+
+Microsoft Defender Antivirus can run alongside Symantec if you set Microsoft Defender Antivirus to passive mode. You can use either Command Prompt or PowerShell to perform this task, as described in the following table:
+
+|Method  |What to do  |
+|---------|---------|
+|Command Prompt     |1. On a Windows device, open Command Prompt as an administrator. <br/><br/>2. Type `sc query windefend`, and then press Enter.<br/><br/>3. Review the results to confirm that Microsoft Defender Antivirus is running in passive mode.         |
+|PowerShell     |1. On a Windows device, open Windows PowerShell as an administrator.<br/><br/>2. Run the [Get-MpComputerStatus](https://docs.microsoft.com/powershell/module/defender/Get-MpComputerStatus?view=win10-ps) cmdlet. <br/><br/>3. In the list of results, look for **AntivirusEnabled: True**.          |
+
+> [!NOTE]
+> You might see *Windows Defender Antivirus* instead of *Microsoft Defender Antivirus* in some versions of Windows.
+
+## Add Microsoft Defender ATP to the exclusion list for Symantec
+
+This step of the setup process involves adding Microsoft Defender ATP to the exclusion list for Symantec and any other security products your organization is using. The specific exclusions to configure depend on which version of Windows your endpoints or devices are running, and are listed in the following table:
+
+|OS |Exclusions |
+|--|--|
+|- Windows 10, [version 1803](https://docs.microsoft.com/windows/release-information/status-windows-10-1803) or later (See [Windows 10 release information](https://docs.microsoft.com/windows/release-information))<br/>- Windows 10, version 1703 or [1709](https://docs.microsoft.com/windows/release-information/status-windows-10-1709) with [KB4493441](https://support.microsoft.com/help/4493441) installed <br/>- [Windows Server 2019](https://docs.microsoft.com/windows/release-information/status-windows-10-1809-and-windows-server-2019)<br/>- [Windows Server, version 1803](https://docs.microsoft.com/windows-server/get-started/whats-new-in-windows-server-1803) |`C:\Program Files\Windows Defender Advanced Threat Protection\MsSense.exe`<br/><br/>`C:\Program Files\Windows Defender Advanced Threat Protection\SenseCncProxy.exe`<br/><br/>`C:\Program Files\Windows Defender Advanced Threat Protection\SenseSampleUploader.exe`<br/><br/>`C:\Program Files\Windows Defender Advanced Threat Protection\SenseIR.exe`<br/>  |
+|- [Windows 8.1](https://docs.microsoft.com/windows/release-information/status-windows-8.1-and-windows-server-2012-r2) <br/>- [Windows 7](https://docs.microsoft.com/windows/release-information/status-windows-7-and-windows-server-2008-r2-sp1)<br/>- [Windows Server 2016](https://docs.microsoft.com/windows/release-information/status-windows-10-1607-and-windows-server-2016)<br/>- [Windows Server 2012 R2](https://docs.microsoft.com/windows/release-information/status-windows-8.1-and-windows-server-2012-r2)<br/>- [Windows Server 2008 R2 SP1](https://docs.microsoft.com/windows/release-information/status-windows-7-and-windows-server-2008-r2-sp1) |`C:\Program Files\Microsoft Monitoring Agent\Agent\Health Service State\Monitoring Host Temporary Files 6\45\MsSenseS.exe`<br/><br/>**NOTE**: Where Monitoring Host Temporary Files 6\45 can be different numbered subfolders.<br/><br/>`C:\Program Files\Microsoft Monitoring Agent\Agent\AgentControlPanel.exe`<br/><br/>`C:\Program Files\Microsoft Monitoring Agent\Agent\HealthService.exe`<br/><br/>`C:\Program Files\Microsoft Monitoring Agent\Agent\HSLockdown.exe`<br/><br/>`C:\Program Files\Microsoft Monitoring Agent\Agent\MOMPerfSnapshotHelper.exe`<br/><br/>`C:\Program Files\Microsoft Monitoring Agent\Agent\MonitoringHost.exe`<br/><br/>`C:\Program Files\Microsoft Monitoring Agent\Agent\TestCloudConnection.exe` |
+
+## Add Symantec to the exclusion list for Microsoft Defender Antivirus
+
+During this step of the setup process, you add Symantec and your other security solutions to the Microsoft Defender Antivirus exclusion list. 
+
+When you add [exclusions to Microsoft Defender Antivirus scans](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-antivirus/configure-exclusions-microsoft-defender-antivirus), you should add path and process exclusions. Keep the following points in mind:
+- Path exclusions exclude specific files and whatever those files access.
+- Process exclusions exclude whatever a process touches, but does not exclude the process itself.
+- If you list each executable (.exe) as both a path exclusion and a process exclusion, the process and whatever it touches are excluded.
+- List your process exclusions using their full path and not by their name only. (The name-only method is less secure.)
+
+You can choose from several methods to add your exclusions to Microsoft Defender Antivirus, as listed in the following table:
+
+|Method | What to do|
+|--|--|
+|[Intune](https://docs.microsoft.com/mem/intune/fundamentals/tutorial-walkthrough-endpoint-manager) <br/><br/>**NOTE**: Intune is now Microsoft Endpoint Manager. |1.

+
+6. On the **Summary** tab, review the settings, and then click **Save**.
+
+### Find a file hash using CMPivot
+
+CMPivot is an in-console utility for Configuration Manager. CMPivot provides access to the real-time state of devices in your environment. It immediately runs a query on all currently connected devices in the target collection and returns the results. To learn more, see [CMPivot overview](https://docs.microsoft.com/mem/configmgr/core/servers/manage/cmpivot-overview).
+
+To use CMPivot to get your file hash, follow these steps:
+
+1. Review the [prerequisites](https://docs.microsoft.com/mem/configmgr/core/servers/manage/cmpivot#prerequisites).
+
+2. [Start CMPivot](https://docs.microsoft.com/mem/configmgr/core/servers/manage/cmpivot#start-cmpivot). 
+
+3. Connect to Configuration Manager (`SCCM_ServerName.DomainName.com`).
+
+4. Select the **Query** tab.
+ 
+5. In the **Device Collection** list, and choose **All Systems (default)**.
+
+6. In the query box, type the following query:<br/>
+
+```kusto
+File(c:\\windows\\notepad.exe)
+| project Hash
+```
+> [!NOTE]
+> In the query above, replace *notepad.exe* with the your third-party security product process name. 
+
+## Set up your device groups, device collections, and organizational units
+
+| Collection type | What to do |
+|--|--|
+|[Device groups](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/machine-groups) (formerly called machine groups) enable your security operations team to configure security capabilities, such as automated investigation and remediation.<br/><br/> Device groups are also useful for assigning access to those devices so that your security operations team can take remediation actions if needed. <br/><br/>Device groups are created in the Microsoft Defender Security Center. |1. Go to the Microsoft Defender Security Center ([https://aka.ms/MDATPportal](https://aka.ms/MDATPportal)).<br/><br/>2. In the navigation pane on the left, choose **Settings** > **Permissions** > **Device groups**.  <br/><br/>3. Choose **+ Add device group**.<br/><br/>4. Specify a name and description for the device group.<br/><br/>5. In the **Automation level** list, select an option. (We recommend **Full - remediate threats automatically**.) To learn more about the various automation levels, see [How threats are remediated](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/automated-investigations#how-threats-are-remediated).<br/><br/>6. Specify conditions for a matching rule to determine which devices belong to the device group.

-## Find and remediate software or software versions which have reached end-of-support (EOS)
-
-End-of-support (otherwise known as end-of-life) for software or software versions means that they will no longer be supported or serviced, and will not receive security updates. When you use software or software versions which have reached end-of-support, you're exposing your organization to security vulnerabilities, legal, and financial risks.
-
-It is crucial for Security and IT Administrators to work together and ensure that the organization's software inventory is configured for optimal results, compliance, and a healthy network ecosystem. They should examine the options to remove or replace apps that have reached end of support, and update versions that have reached end of support. It is best to create and implement a plan **before** the end of support dates.
-
-To find software or software versions which have reached end-of-support:
-
-1. From the Threat & Vulnerability Management menu, navigate to **Security recommendations**.
-2. Go to the **Filters** panel and look for the tags section. Select one or more of the EOS tag options. Then **Apply**.
-
-    ![Screenshot tags that say EOS software, EOS versions, and Upcoming EOS versions](images/tvm-eos-tag.png)
-
-3. You will see a list recommendations related to software that is end of support, software versions that are end of support, or upcoming end of support versions. These tags are also visible in the [software inventory](tvm-software-inventory.md) page.
