I installed Backup Exec 16 to my server.
And I would like to upgrade it to 21.
I have created a VM to test the upgrade processing. I used the trial versions to test the upgrade. It didn't have any error.
However, It showed a message that "Entitlement IDs for previous versions of Backup Exec are not valid in this version of Backup Exec(TM)."
Is that means the licenses of Backup Exec 16 cannot pass to 21 ?
And when I upgrading Backup Exec 16 to 21, what things not including in below article that I need to pay attention?
