![]() You'll need to update the deployment share after changing this setting. Disabling multicast will speed up deployment there are only a few computers. If you have a limited number of simultaneous deployments, you should disable multicast which was configured in a previous procedure in this guide. Multicast is a technology designed to optimize simultaneous deployment to multiple devices. You can control data within and outside the user profiles. ![]() In addition to the command-line switches that control which profiles to migrate, XML templates control exactly what data is being migrated. For example, adding /uel:60 will configure ScanState (or LoadState) not to include profiles that haven't been accessed for more than 60 days. You also can combine the preceding switches with the /uel switch, which excludes profiles that have not been accessed within a specific number of days. You can limit which profiles are backed up by configuring command-line switches to ScanState (added as rules in MDT).įor example, the following line configures USMT to migrate only domain user profiles and not profiles from the local SAM account database: ScanStateArgs=/ue:*\* /ui:CONTOSO\* If you have a computer that has been in your environment for a while, it likely has several domain-based profiles on it, including those of former users. Multi-user migrationīy default, ScanState in USMT backs up all profiles on the machine, including local computer profiles. Using this backup to restore the entire computer is not a supported scenario. Please note that this is a data WIM backup only. wim file contains the entire volume from the computer and helpdesk personnel can extract content from it if needed. wim file is created in addition to the USMT backup. In addition to the USMT backup, you can enable an optional full Windows Imaging (WIM) backup of the machine by configuring the MDT rules. When you use this feature, the files are linked in the file system, which allows for fast migration, even when there's many files. ![]() Wipe the partition, except for the backup folder.ĭuring the computer refresh, USMT uses a feature called Hard-Link Migration Store.Back up data and settings locally, in a backup folder.To complete a computer refresh, you will: The computer refresh processĪ computer refresh isn't the same as an in-place upgrade because a computer refresh involves exporting user data and settings then wiping the device before installing a fresh OS and restoring the user's data and settings.įor a computer refresh with MDT, you use the User State Migration Tool (USMT), which is part of the Windows Assessment and Deployment Kit (ADK) for Windows 10, to migrate user data and settings. For more information on the setup for this article, see Prepare for deployment with MDT. The example used here is a computer running Windows 7 SP1.īoth DC01 and MDT01 are running Windows Server 2019 however any supported version of Windows Server can be used. PC0001 is a domain member computer running a previous version of Windows that is going to be refreshed to a new version of Windows 10, with data and settings restored.MDT01 is domain member server that hosts your deployment share.DC01 is a domain controller for the domain.For more info on that scenario, see the USMTOfflineMigration property on the MDT resource page.įor the purposes of this article, we'll use three computers: DC01, MDT01, and PC0001. MDT also supports an offline computer refresh. In this article, the computer refresh will be done while the computer is online. You can also use this procedure to reinstall the same OS version. The computer refresh scenario is a reinstallation of an updated operating system on the same computer. ![]() This article will show you how to use MDT Lite Touch Installation (LTI) to upgrade a Windows 7 computer to a Windows 10 computer using the online computer refresh process.
