Hey folks,

I upgraded my first 10.x server to 10.3.3 at the end of last week, and after upgrading all the Primaries, the customer's ZPM licence was flagged as expired and we couldn't remediate or cache new patches.

After a bit of head scratching, we generated a new ZPM activation key using his ZPM 11 licence in NCC, and after inputting the key, ZPM came back to life.

It may have been a one off, but it may save someone a bit of time later if it happens again.
