Hello,


I am doing a simple migration of CUCM 8.5.1 from MCS to UCS VM's. I know the process of DRS, VM build, restore and relicensing but I was wondering in the case of a simple migration, not upgrade, if there was any preference to doing the subscribers first then the pub of vise versa.


thanks

Hello Bill,


1- Install the VMware on the UCS

2- Then you can easly install the same version 8.5.1 on the UCS

3- Backup from MCS server

4- Restore on UCS

5- Rehost the Licesnes


then you can install your subscribers.


What do you mean with "doing the suberscriber first" ?
