So - following from my previous question: How do I stop DFSR replication preventing a Domain Controller from advertising Domain Services?, I lost the FSMO DC, and my only other DC was in an unrecoverable state.

I've created a new domain to continue my testing, but now have an issue which I suspect is relevant to any domain suffering a "catastrophe".

I have user accounts and client PCs "on the old domain". (Actually 1 client PC and 3 accounts)

I can still sign into the client PC as any of those users on the "dead" domain, because that is cached.

There are (thankfully) no encrypted files in the "old" domain.

What I would now like to do is migrate the full content (files, preferences, etc) from the "dead" domain to the new "live" domain for any/all user accounts, for the "old" PC.

Is there anything out there which can assist me in doing so?
