CM 3.3.3 Upgrade to 4.X

Unanswered Question

Have upgraded 3.3.3 to 4.3.2 and noticed a change that has the tech concerned.

In CM3 I have two route groups. After the upgrade I have two new listings, so four groups.

RLCMG_CM_ip Address of one subscriber and a second entry with the other subscriber IP.


Is this "normal"?

Is it something to be concerned about?

Can I just delete these uneeded groups and press on?

Hi Lee,


Have a look at these related notes


Reassigning Route Lists


If you had more than one primary Cisco Unified CallManager server in a cluster and you are upgrading from Cisco CallManager Release 3.3(x), to Cisco Unified CallManager 4.3(1), you will need to reassign the route list to the Cisco Unified CallManager group that you configured in Cisco Unified CallManager Administration to maintain optimal load balance. To ensure call processing redundancy, the upgrade program created a Cisco Unified CallManager group containing a primary server and a backup server for every primary Cisco Unified CallManager server in the cluster and then assigned route lists to each Cisco Unified CallManager group using a round robin algorithm. The name format for the created Cisco Unified CallManager group is RLCMG_.


Procedure


Step 1 Evaluate the Cisco Unified CallManager group and route list configuration for load balancing and redundancy, as described in the Cisco Unified CallManager System Guide and the Cisco Unified CallManager Network Solutions Design Guide.


Step 2 Assign the route list(s) to the Cisco Unified CallManager group(s) that you have configured in Cisco Unified CallManager Administration.


Step 3 Delete the migrated CCM group, RLCMG_.
