I have set up another ZCS server and am trying to move mailboxes from one to the other. In the Administration Console, I choose the account and tell it to "export" the mailbox to the "target server". That seems to go well until I ask it to "verify". It fails with a domain unknown error. However, if I ignore that and purge the original. I can log into the Collaboration Suite just fine. I can even see things liked to it in other mailboxes.
Now, when I try with my account, the web mail works just fine, but I lose all access to from my iPhone. Move it back, and everything works again. There is certainly a configuration problem, but since this is the first time I've tried multiple servers, I clearly don't have a great amount of experience. I did install and configure per the documentation. I have looked through the wikis. I have Googled. I'm tempted to fill this first post up with "zmprov gacf" from both servers, but instead I'll offer to provide whatever information anyone might request.
If anyone can point towards something to try, I would appreciate it.
