If the virtual machine already contains nodal licenses and the PLDS Host ID changes, the licenses remain valid for a 30-day grace period. During those 30 days, if you make more than five further changes to the configuration parameters existing licenses become invalid immediately. Therefore, it is recommend that you finalize all these parameters before acquiring any licenses from Avaya.

If the primary server using PLDS licenses goes down for any reason, then the secondary server will only have a grace period of 15 days before invalidating the licenses.
