Very disappointing to get no response. I followed the instructions for upgrading servers by moving prefs. So that no mail was lost, I started up the new server. I then archived each mail folder (inside domains) off the old server and moved to the new server. As each domain was copied to the new server, I then merged the extracted files to the new mail folder. Very slow and tedious moving so much mail.

There was a lot of information on the old forum related to this topic.  SmarterTools promised to keep it available for searching, then they used some bogus justification to remove all of it -- without asking for any input from the community.  It's a shame, and tells you something about their evolving mindset.  Many of us here were former Imail users who got tired of the deaf ears.  I hate to see it happening again.
