Ole,

     Can you explain why you need to move the FSMO roles? From your 
explanation I don't see it as necessary. Creating sites and subnets is 
very straightforward if using the RSAT from Microsoft. I can share those 
steps.

Will you have access to both facilities through your network during the 
move?
