A couple of quick questions regarding upgrading Backup Exec from version 15 to version 20.3:
Can tapes that were written with version 15 be read and restored with version 20.3 if we upgrade?
We currently run Backup Exec 15 on Windows Server 2012 R2 and will be upgrading the servers to Windows Server 2019. Can Backup Exec 15 run on Windows Server 2019? (no documentation states this compatibility)
Is it possible to do an in place upgrade that will keep our configurations the way they are so we won’t have to set everything up from scratch?

Tapes written in previous version of BE can be restored/catalog etc in BE 20.x.
