[cisco-voip] Upgrade 4.1(3) to 6.1(2) with cluster split

[Ryan Ratliff]

If you want to use DMA to migrate the data and licensing then yes, you need
to split the cluster at 4.1 and then use DMA.  Since you have the new
servers as long as you have the OS software that supports the new models
this should be pretty easy to do.  Otherwise you are looking at going the
manual route for DLUs etc which I understand can be a bit frustrating.

Subject: [cisco-voip] Upgrade 4.1(3) to 6.1(2) with cluster split


I currently have a cluster of 7 servers (7835) running CUCM 4.1(3).  We have
8 new servers which will run 6.1(2), and our single existing cluster will be
divided into two to segregate CTI traffic for the Call Center.
 
Does anyone have a recommendation for the best methodology to follow for
this upgrade?  We would like to build the 2 clusters in the sandbox with all
of the migrated information and licensing in place, then cut all at once if
possible.
 
What is the best way to handle getting DLUs generated.  DMA would generate a
single license file...we need 2 files.  Do I have to build these new
servers/clusters on 4.1 first then DMA them?
 
I apologize if this has been covered and I missed it.
