How to migrate users in different Notes domain?

Can i know how to migrate users in different Notes domain? Currently i have two Domino svrs (different Notes domain) which had cross certified between each other.However, when try to migrate users to the other server using “Move to another server”, i got the error stated that cannot move mail file from old server to new server due to different Notes domain in Server document.

Any idea?
