Are old license keys necessary?

[terryd3]

I have license keys on our NetBackup host that go back over ten years.  Should I ever delete the old keys, and if so how often?

If they have expired, yes, delete them.

How often, is up to you.

When I run get_license_key command they all say "Expires: No Expiration Date".  I add new license keys every time I upgrade the system.  Even though they have no expiration date, can I still delete all of the older keys when I add the new ones?

terry, if the new license keys provide you with the same license and quantity as the old licenses keys, then yes, delete the old ones, but keep a note of them just in case you have to add them back :)

Once you have added new license keys for new NBU version, there is no need for previous version license keys.

Not a requirement, but best for tidiness and to avoid confusion - delete previous version license keys.
