we are plannig to upgrade our existing CUCMBE 6.1 to Call Manager Cluster CUCM 7.1 & unity Connection 7.1.
call Manager cluster with 2 servers.one as publsiher/backup subscriber in MCS-7845 & 1 deticated Subscriber in MCS-7845.
One server for untiy connetion 7.1 in a MCS-7845 server and other server for Unity Presence.
In cisco website i can find out the upgradation path for CUCMBE 6.1 to CUCMBE 7.1 etc , but no where cannot find a document for migration CUCMBE server to a Call Manager cluster.
Could any one can guide me, how can I do the upgrade from CUCMBE(CUCM 6.1 & Unity Connection 2.1 on a single server) to CUCM 7.1 in one server & unity connection in another server.
Thanks & Regards,
