We use Folder Redirection with offline folders. There are ~200 users whose My Documents is redirected to a server. GPO is in place for the folder redirection part and offline folders are enabled by default. There is no policy setting for offline folders.
The current file server is a Windows Server 2003 system. The new file server would be a Windows Server 2008 R2 system in a different domain than the current one. End users are on Windows 7.
I would like to know the best approach to get this migrated across with little or no impact. Let me know if more details are required.
