Unsynchronized offline files are not migrated when you use USMT 5.0

When you try to migrate offline files data by using Windows User State Migration Tool (USMT) 5.0, unsynchronized data may be ignored in the migration. Additionally, when you examine the scanstate debug logs, you notice the following plug-in errors. (Error text is wrapped for readability.)

Windows XP source computer

Windows 7 source computer

Note The following functionalities and limitations apply to online USMT migration of offline files (also known as client-side caching or CSC):

• USMT 5.0 does migrate CSC settings and the "dirty" (unsynchronized to server) file cache from Windows 8 source computers.
• USMT 5.0 does migrate CSC settings from Windows Vista, Windows 7, or Windows XP source computers However, USMT 5.0 does not migrate the "dirty" (unsynchronized to server) file cache from these operating systems because the cscmig.dll and cscmigdl.dll plug-ins are not included with USMT.
• USMT 4.0 does not migrate CSC settings or the "dirty" (unsynchronized to server) file cache from Windows XP source computers.
• USMT 4.0 does migrate CSC settings and the "dirty" (unsynchronized to server) file cache from Windows Vista and Windows 7 source computers.

In order to migrate the CSC dirty cache, USMT must have plug-in DLLs that are provided by Offline Files. USMT 5.0 does not include the plug-ins in the USMT installation package, even though it does include the necessary XML manifests. If you migrate without capturing the CSC dirty cache, the offline data is permanently lost after the source computer is gone. (Dirty cache CSC data is the local changes that have not yet synchronized back to the file server.)

USMT does not support offline migration of CSC files because plug-ins cannot be used in /offlinewinold or /offlinewindir migrations.

Outside USMT

To work around this issue outside USMT, have end-users manually synchronize so that all offline files are up to date on the file server. This can also be automated by using the Synchronize method of the Win32_OfflineFilesCache class. For example, go to the following websites:
Using USMT

To work around this issue by using USMT, use the migration DLLs that are included with the destination OS to correctly migrate CSC cache data by using USMT 5.0 (only) from any source operating system that is supported by USMT to any destination operating system that is supported by USMT. These files are already tested and supported through Windows Upgrade and Windows Easy Transfer (also known as WET or File And Settings Transfer Wizard).

Important

• In the following examples, USMT 5.0 is installed in C:\usmt. Your path may differ.
• In the following examples , the C:\windows\winsxs folders are specific to the operating system service pack, build, and hotfixes. Your path may vary. Always use the latest file from the appropriate operating system and architecture.

The inability to migrate offline files in these scenarios and not having the migration DLLs in the USMT package represent a code defect and are not a result of product design.

USMT does not support or use plug-ins when it performs offline migrations of any kind (/offlinewinold or /offlinewindir). This behavior is by design.
