CUCM/IM&P and UCXN Migrations

[mattiep00]

Hi,

I am interested in others strategy in migrations from CUCM/CUPS 8.x to 10.x, and UCXN 8 to 10.x. (P2V for all)

I am thinking of using PCD to migrate the CUCM/IM&P and change hostname/IP Addresses for a staged migration to bring them up in parallel prior to cutover. Has any one else done this, and considered how existing Jabber/CUPC users are affected? E.g If I want to migrate users in stages, how do I perform the necessary DNS changes so that only subsets of users are affected at a time? (Eg. Site by Site)

For UCXN, seeing as PCD is not yet supported, I was thinking of building a new UCXN cluster from fresh (instead of the usual DRS backup & restore) and then using COBRAS to migrate the data on the cutover day. If I do DRS method, I need to build up the lab with the different IP Addressing so it seems much cleaner building from scratch...Has any one else also gone down this path?

Basically I need to have as minimal impact to the users as possible. Any one else's thoughts or strategies would be much appreciated!

Thanks

How many users are you talking about? I've migrated a tons of these before PCD came about, and smoothened out my own process to the point I'm not using PCD on my radar. I have several coworkers whom have tried using PCD, and had mixed results bordering on some of them losing their mind trying to get PCD to work.
