If so use the AMStool.exe in c:\program files\Alwil software\Management tools.
Take a backup of the database!
Do a fresh install of ADNM and restore the database, remembering to import the license.dat with the amstool.
You`ll need to also do a discovery but all the machines should look for a new AMS if they can’t connect to the old one. If you can give the new server the same ip or name as the old to make it even smoother.
