Folding Registry Value

If I want to reformat a machine while a work unit is in progress, can I stop the service, export the PandeGroup registry entry…ie HKEY_LOCAL_MACHINE\SOFTWARE\PandeGroup and when I move onto the new machine copy import this back into the registry and have all the folders moved back to the same places and have it continue on with the same work it left off with and count as the same CPU active on the FAH website?

Yes. take that key and the following files

\work (folder)
queue.dat

and
fahlog.txt and unitinfo.txt if you like.
