I upgraded my backup exec 2012 to BE16. But all old agent license can't re-generate a new license file for BE16 (only support gererate BE14 license file).
Do I need buy new agent license?
Is BE16 not support BE2012 agent licenses? Our old agent (linux/windows/VM) license files bought from 2013.
You would request a new license file for BE 16 and it would be made available to you. As soon as you install it on the media server you're good to go. But it doesn't prevent you from push-installing any RAWS agents.
Do you have active maintenance in place?
I have moved your post in the General Veritas forum to the Backup Exec forum.
If your annual maintenance is up-to-date, you would've received a license certificate from Veritas with your updated Entitlement. You can logon to MyVeritas , select Licenses -> Entitlements.
You will be able to generate and download your BE16 license keys here.
