I have a main file-server that has been in operation for some time now. However it is just a file server, so we've decided to look at a "virtual" replacement.
In the past I needed to do something similar with a Debian Linux box.
I created the new virtual server and then using Rsync I left the two servers in effect "mirroring" one another for about a week. At the end of the week I shut down the old server, gave it's identity to the virtual server and that was it.
After 10 minutes of downtime nobody even knew that they were accessing a new server for all the old data - nothing needed changing except at the back-end.

So my plan was to do the same with the Windows server. To have both the current server and it's "to be" virtual replacement running at the same time for a period where both servers contain all of the data and more importantly retain all of their active directory permissions. Then at a point in the future shut-down the current server, give all it's identity to the new one and away we go.

Is there a tool like Rsync for Windows that will allow me to do this?

Cheers for any input.
 
DFS replication. Once you've made the initial copy (e.g. out of hours) you can maintain a read-only mirror very easily.

The other advantage with DFS is your network clients won't experience any down-time at all as the transition should be transparent. Ok it's not quite instant but at worst there shouldn't be any more than 20-30 seconds of inaccessible shares.
