Data Migration Assistant (DMA) to move phones from 4.1 to 5.1 cluster?

Unanswered Question

IS DMA only for upgrades or can it be used for migration?


We have a customer with two clusters. One is a 4.1(3) cluster and the other is a 5.0 cluster. We plan to do the following

1. upgrade the 5.0 cluster to 5.1

2. migrate the phones on the 4.1(3) cluster to the 5.1 cluster

3. rebuild the servers in the 4.1 cluster as subscribers to the just upgraded 5.1 cluster.


Question is for step 2). Can I use DMA to migrate users from one 4.1 cluster to a 5.1 cluster? Or is DMA used only for upgrading callmanager from within the same cluster?

DMA can only be used to migrate Data when the server was upgraded. It cannot be used to migrate Phone and User information after the upgrade is complete. AFAIK, there is no tool available to migrate Data from CallManager 4.x to 5.x after the installation/upgrade is complete.


Also, do note that the only restore option available with CM 5.x is using DRS which is an inbuilt tool used to backup and restore CallManager 5.x. For more information on DRS, please refer:
