I'm plagning to migrate a Callmanager Cluster from 4.2 version to 7.1next week, but my customer tried to patch the 4.2 version and the patch failed in the subscriber (Now the servers system version in the Publisher is 4.2(3)SR2 and in the subscriber is 4.2(3)SR1/ the Installation ID in the Publisher is CCM4.2(3)SR2 and in the subscriber is 4.2(3)).
Can I execute the DMA in Publisher in this state or i must synchronize the both servers before ?
Again...this is just my opinion, but I would stick with 7.1(3b)SU2. The latest
Patch for 7.1(5) has only been out 12 days and it's predecessor only lasted
3 days before being replaced. I'm sure the VG248 will be fine with 7.1(5) if you
chose to go that route.
If it were me I would want everything working properly on the Cluster before
running the DMA The upgrade of the current Sub to 4.2(3)SR2 wouldn't
take too long and would buy you some peace of mind. I'm guessing that
for TAC support this would be a requirement as well.
Just my thoughts my friend,
