DESCRIPTION: How do upgrade a windows server split mode configuration?
During the upgrade process for split mode on a Windows server environment a couple of tasks have to be performed
This is the process:
Stop all services on the CC and keep them stopped. Upgrade the RA’s one at a time. The RA will reboot during the update, mail flow will stop to that box while that occurs. Repeat that process for each RA until all are done. If there is a CC/RA combo treat this as a CC and not an RA. When all RA’s are upgraded, then upgrade the CC (the services are still stopped) Upgrading the CC will also require that it reboots.
At anytime during the upgrade if a server (CC / RA / or otherwise) doesn’t reboot , make sure the upgrade processes are finished completely and do the reboot manually. After the reboot is done, verify that the upgrade is complete.
