change of campus contact

Is there a knowledge article that outlines what all needs to be done when a main TDX contact on campus is moving on? If not, this could be the start of one. :)

As an admin, I can get the person set up properly in our instance. I can also get the replacement set up in groups and following questions on the TDX sites. But...

How do I convert all the active tickets / enhancement suggestions to have the new person being the requestor?

Is there some list that TDX has at the business liaison level that needs to be updated? Sometimes I get non-marketing messages outside the system and I'm not sure where that info is.

Are there things I'm not thinking of?

If you have a checklist, that would be great.
