Install CallManager 4.1(3)sr3a sub into a 4.1(2)sr1 cluster?
I am tasked with building a Subscriber for a CCM 4.1(2)sr1 cluster and only have 4.1(3) media available onsite. Would this work OK? I plan on upgrading both to a common version later, but need to get Sub going asap. Thanks! George
"You cannot add a subscriber server to a cluster by installing a previous version of Cisco CallManager and then upgrading the subscriber server to the same version that is running on the publisher server. If you are adding a new subscriber server or replacing a subscriber server on the cluster, you must use the installation CDs with the same Cisco CallManager version that is running on the publisher server."
Since you have 4.1(3) media you can upgrade the Publisher to 4.1(3) and then install the Subscriber.
