Hi,
I'm intending to re-generate the license files as the mac address will probably be different.
About the server name, I believe that keeping the name is enough for the Inventor/ACad network client to keep working and not making me re-image the deploy.
I just say this because in the installations, when you indicate the server name, it just seems to do a simple search via network neighborhood (wins) or dns at most.
Are you sure that it keeps track of the server's mac address? That wouldn't make much sense from the developers, but it could be. Hope not!!
