> We are introducing a new version of the Device Guard Signing Service (DGSS) to be more automation friendly. The new version of the service (DGSS v2) is now available. As announced earlier, you will have until the end of December 2020 to transition to DGSS v2. At the end of December 2020, the existing web-based mechanisms for the current version of the DGSS service will be retired and will no longer be available for use. Please make plans to migrate to the new version of the service by the end of December 2020.

> Following are the major changes we are making to the service:
> - The method for consuming the service will change to a more automation-friendly method based on PowerShell cmdlets. These cmdlets are available as a NuGet download, https://www.nuget.org/packages/Microsoft.Acs.Dgss.Client/.
> - In order to achieve desired isolation, you will be required to get a new CI policy from DGSS v2 (and optionally sign it).
> - DGSS v2 will not have support for downloading leaf certificates used to sign your files (however, the root certificate will still be available to download). Note that the certificate used to sign a file can be easily extracted from the signed file itself. As a result, after DGSS v1 is retired at the end of December 2020, you will no longer be able to download the leaf certificates used to sign your files.

When you use the Device Guard signing portal to sign a catalog file, the signing certificate is added to the default policy. When you download the signed catalog file, you should also download the default policy and merge this code integrity policy with your existing code integrity policies to protect machines running the catalog file. You need to do this step to trust and run your catalog files. For more information, see the Merging code integrity policies in the [Device Guard deployment guide](/windows/device-security/device-guard/device-guard-deployment-guide).
6. Open the root certificate that you downloaded, and follow the steps in **Certificate Import wizard** to install the certificate in your machine's certificate store.
7. Deploy signed catalogs to your managed devices. For more information, see Deploy catalog files with Group Policy, or Deploy catalog files with Microsoft Endpoint Manager in the [Device Guard deployment guide](/windows/device-security/device-guard/device-guard-deployment-guide).
