[cisco-voip] FW: DMA - from 4.1.3 to 7.1

[wael ahmed el mezain]

 Dears,

 
- I have a client has 4.1.3 cluster and we going to upgrade to 7.1. 
- The migration will be done at new servers as the old servers not support the 7.1
- We already copied the DMA files and everything working fine at the new servers but the 7.1 still off-line (the old servers "4.1.3" still live)
- The downtime postponed many time regarding to 3rd party voice application issues. (more than 30 or 45 days)
 
- within this period the client had many many changes at the old server 4.1.3 (add/removing/changing many configuration)
 
- Is there any way to move only these changes only or I have to run the DMA again and re-install the new servers at the 7.1 clusters (which took +2 or 3 days from me before) ?
 
- If there is no way, can we re-install the Pub only at the 7.1 cluster or we have to re-install all the Sub also (as the PDF saying) ?
 
Thanks,
Wael
