We are about to change the Call Managers Domain due to a recent merger. The old Domain was used on the outside and the inside but the new Domain is XYZ.com on the outside and XYZ.corp on the inside. Although I don't think that makes a difference.
My questions is: Is there a paper or a set of instructions that would allow me to create a checklist to change all the appropriate Domains on the servers as well as Certificates and anything else that I simply don't know. We have a setup of the CUCM (pub and sub) Unity (p&s) IM&P (p&s) two (2) Expressways c's and one (1) Expressway E
The funny thing is about the Expressway E is that at the time we set this up years ago the engineer at Cisco assisted us and said we just needed one Expressway E to handle all traffic coming in. I pretty much took his word for it and have never looked back since. After the migration I'm going to look into how to set up the second Expressway E to resolve this.
