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?
