If the server is hosting its own licenses, then Avaya validates each license against the server's unique PLDS Host ID. For an IP Office virtual machine, the IP Office generates the PLDS Host ID based on the following factors:
Deployment Specific Factors:
The PLDS Host ID is partially based on several factors relating to the particular virtual machine's deployment. Redeploying the virtual machine changes its PLDS Host ID, thus existing licenses in IP Office configuration becomes invalid. To move to another virtual server platform without requiring new licenses, use vMotion.
Configuration Specific Factors:
The PLDS Host ID is also partial based on the following parameters of the virtual machine. Changing any of these parameters changes the virtual machine's PLDS Host ID:
Host Name
LAN1 IP Address
LAN2 IP Address
Timezone
DHCP Mode
