[PVE-User] Transfer of lisens

[Amir M. Ahmed]

Hi

I am planning to upgrade from PVE 3.4 to PVE 4.1.
I have 4 identical servers an two of them are running PVE 3.4 cluster
with licenses.

Can I transfer the cluster running PVE 3.4 onto  server 3 and 4 with PVE 
4.1 and use the same
license keys?

Thanks,
Amir
