Moving secondary CUCM/UC to another deployment model

[harisivaji]

Hi,

The scenario: Our Client company has been functioning with 2 subscribers and 1 Publisher along with 1 Unity connection server in centralized deployment model. Now there is a requirement, where we need to convert the deployment in to Clustering over WAN deployment by adding one more subscriber and one UnityConnection as Secondary servers but from a remote location.
Thus converting a centralized to Clustering over WAN depolyment.
Is there ant limitations or problem we may face when we are doing this.

Make sure that the round trip time for communications between the servers is within specifications (depends on CUCM version what the time is).  You can check this from the Cisco Unified Reporting Tool by running a cluster overview report.
