### Deploy the Upgrade Readiness deployment script
You can use the Upgrade Readiness deployment script to automate and verify your deployment.
See [Upgrade Readiness deployment script](upgrade-readiness-deployment-script.md) for information on obtaining and running the script, and for a description of the error codes that can be displayed.
>After data is sent from computers to Microsoft, it generally takes 48 hours for the data to populate in Upgrade Readiness. The compatibility update KB takes several minutes to run. If the KB does not get a chance to finish running or if the computers are inaccessible (turned off or sleeping for example), data will take longer to populate in Upgrade Readiness. For this reason, you can expect most your computers to be populated in OMS in about 1-2 weeks after deploying the KB and configuration to user computers.
## Deploy Upgrade Readiness at scale
When you have completed a pilot deployment, you are ready to automate data collection and distribute the deployment script to the remaining computers in your organization.
### Automate data collection
To ensure that user computers are receiving the most up to date data from Microsoft, we recommend that you establish the following data sharing and analysis processes.
- Enable automatic updates for the compatibility update and related KBs. These KBs are updated frequently to include the latest application and driver issue information as we discover it during testing.
- Schedule the Upgrade Readiness deployment script to automatically run so that you don’t have to manually initiate an inventory scan each time the compatibility update KBs are updated.
- Schedule monthly user computer scans to view monthly active computer and usage information.
>When you run the deployment script, it initiates a full scan. The daily scheduled task to capture the deltas is created when the update package is installed. For Windows 10 devices, it's already part of the OS. A full scan averages about 2 MB, but the delta scans are very small. The scheduled task is named **Windows Compatibility Appraiser** and can be found in the Task Scheduler Library under Microsoft > Windows > Application Experience. Deltas are invoked via the nightly scheduled task. It attempts to run around 3:00AM every day. If the system is powered off at that time, the task will run when the system is turned on.
### Distribute the deployment script at scale
Use a software distribution system such as System Center Configuration Manager to distribute the Upgrade Readiness deployment script at scale.
