I'm using Google Apps for Domain to manage mail, calendar, docs, etc for pupeno.com. I've created many other domain names and added to that Google Apps account as aliases.
Now I want to move some of those domains names to be aliases of another Google Apps account. What's the best way to change the alias? Any way to transfer? If I delete it for one account and activate it for the other, how long will I spend without access in the meantime?
Update: completely rephrased the question and added screenshot because it was hard to understand.
