Integrations > RealPresence Resource Manager and terminate the integration. 

b Go to Network > Site Topology > Territories and reassign the cluster’s territory responsibilities. 

Wait a few minutes and verify on another cluster that the change has been replicated. 

c Go to Network > DMAs and take it out of service (or busy it out and wait for all calls to end). 
d Select this cluster and click Remove from Supercluster. When asked to confirm that you want 

to remove the cluster, click Yes.

Caution: Rejoin the correct cluster
Be sure you select the cluster you just downgraded (the one you’re logged in to) and join it to another 
cluster, not the other way around.
