I've been told, if I replace our current Pub with new hardware, I will have to rebuild both subscribers. Is this correct?
We have currently one Publisher and two subscribers.
I have built a new Publisher on new hardware with the same CUCM version, migrated licenses and MAC and restored the backup database. When I tested the new Pub live, I came across database replication issues, the Pub couldn't see the two Subs or viceversa.
Is there any workaround or a fix, to replace the Pub without having to rebuild the subscribers.
Sadly, the ability to replace the Publisher Node without
reinstalling the Subscriber Nodes was not introduced until
CUCM 7.1(2) or 7.1(3) Here is the related info for your
Replacing the Publisher Node
Complete the following tasks to replace the Cisco Unified Communications Manager publisher server. If you are replacing a single server that is not part of a cluster, follow this procedure to replace your server. Caution If you are replacing a publisher node in a cluster, you must also reinstall all the subscriber nodes and dedicated TFTP servers in the cluster, after replacing the publisher node.
You can try all the dbreplication tools from the CLI, but by the time those get done running and rebooting a node here and there, its just easier to rebuild the subscriber I have found. Its only about 1-2 hours of time per subscriber to bring it back to normally operation in the cluster.

the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
