Has anyone here encounter this problem?
Here is the solution I did before:
1.Backup the database (the database where the backup was copied is the new database)
2. install the SEPM12.1.2(RU2)
3. redirect the SEPM12.1.2(RU2) database to the sql server where I put the backup.
done, but of course I already close running services of SEPM and other things.
But how about if a SNAC is running with the SEPM?
