Changing server FQDN without breaking backup jobs

Hello,

We just renamed our primary domain.

I now have issues with all of the servers in Backup Exec that we used to backup. The FQDN of all of our servers has changed, so BackupExec is treating them all as new servers.

Is there a way we can just change the existing servers to match the new FQDN so we don't lose our job history?

All the servers have Windows Server OS. Most of them have Windows Server 2008 R2 but the older ones still have Windows Server 2003 SP2 and the newer ones have Windows Server 2012 R2.

Maybe it is something obvious but I am just a beginner and I didn't find anything on this issue.

Thanks in advance.
