I'm in the process of migrating a company from a single-label domain & forest, "domainname," to a new "newdomainname.local" domain & forest. EX2013 single-server installed and working on both domains, including autodiscover. Trust is set up and works, cross-domain DNS works from both sides. However...
I can create a Migration Endpoint on ex2013.domainname that points to ex2013.newdomainname.local, but when I try to add a mailbox created in newdomainname.local, none are displayed.
I can't create a Migration Endpoint at all on ex2013.newdomainname.local. I get a message that starts, "We couldn't detect your server settings. Please enter them. AutoDiscover failed with a configuration error: The migration service failed to detect the migration endpoint using the Autodiscover service."
I'm prompted for the FQDN of the other Exchange server. When I enter ex2013.domainname, I get, "Error: The connection to the server 'ex2013.domainname' could not be completed."
Is this expected when one server is on a single-label domain? Is there a way to enable me to use mailbox migration?
TIA
