If I understand your question, you want to merge unrelated workloads on physically disparate CEC's.

Personally, I'd call this a migration.
Assuming both CEC's are on the same OS & CICS release, the high altitude overview is to do a logical backup of the CICS regions. Restore it to the new CPAC and establish the CICS regions.
When the CICS regions are running ok and coming up/down on schedule, it's time to consider moving the application. This part is pretty vanilla - logical backup, def gdg's, restore/rollin, etc.
(While you're doing this, your network people should be paralleling network access to the new CEC.)
The actual cutover is up to you, cold turkey or phased cut-over.

I realize this is amazingly vague, but you've asked a question that people build entire careers on. It's impossible to explain that in a couple paragraphs.
