I have a customer with 1 CM Pub and Sub on version 4.1(3). I added a second subscriber with the same exact version and SR patches. Problem I'm running into is in SQL Enterprise Manager, the replication fails and it complains of "COuld not find stored procedure "IsChangeNotifyReady"". I looked at the Pub and the stored procedure exists. Any ideas? Database names are the original CCM0300 across the board.
Have a look at these good docs;
Reestablishing a Broken CallManager Cluster SQL Subscription with Cisco CallManager
Using DBLHelper to Reestablish a Broken Cisco CallManager Cluster SQL Subscription
Hope this helps!
