Can we join an existing CUCM Subscriber to new Publisher (Cluster)?
Let's say we have an existing Cluster of CUCM:
- CUCM-A Publisher 11.5 version
- CUCM-B Subscriber 11.5
- CUCM-C Subscriber 11.5
We shutdown the Publisher CUCM-A, and we install a new publisher with 12.5 version.
Can we join the subscribers CUCM-B and CUCM-C to the new publisher?
You need to build new subscribers in V12.5.
Can we join the subscribers CUCM-B and CUCM-C to the new publisher? Not possible.
