In duplex Communication Manager servers, you need to first upgrade the standby Communication Manager server, and then the active Communication Manager server.
Use the procedure to upgrade duplex Communication Manager to Release 10.2.x from:
-
Release 7.x running on Appliance Virtualization Platform or on VMware.
-
Release 8.x running on Appliance Virtualization Platform or on VMware.
-
Release 10.1.x running on Appliance Virtualization Platform or on VMware.
Note:
From Release 10.1, Appliance Virtualization Platform is no longer available. Therefore, if Communication Manager Release 8.1.x and earlier is on the Appliance Virtualization Platform host, then migrate Appliance Virtualization Platform to Avaya Solutions Platform 130 Release 5.x before upgrading Communication Manager to Release 10.1. Migration of Appliance Virtualization Platform is supported from Avaya Solutions Platform 120 (Dell PowerEdge R640).
The procedure covers upgrades and migration to a new server.
