4.1 to 5.1 Upgrade Issue

Brian Carscadden · ‎01-21-2009

Upgrade of publisher succeeded. However when the subscriber was added we immediately lost 80% of the phone registrations. There is only one Callmanager group with the subscriber first, then publisher. If I stopped the CM service on the sub, all phones register normally to the publisher. Issue appeared to be a DB replication error, but resyncing (utils dbreplication reset) didn't work, nor did rebuilding the subscriber entirely. Any ideas?

After you add a new subscriber to the cluster, the replication agreements and the actual replication are initiated only after the first reboot of each subscriber. So make sure you reboot the subscribers after you add them to the cluster. If you add many subscribers, reboot them one at a time in order to avoid overloading the publisher with the database replication.
