I've had a few test runs at migrating iredmail.

The problem I'm up against at the moment is that I'm unsure how to migrate accounts & aliases, or more accurately, the information you see when you log into /iredadmin.

I've migrated /var/vmail, and imported sql for amavisd, cluebringer, iredadmin, roundcubemail, vmail. I can log into roundcube and see my emails. But I can not send emails from my alias accounts, and if I log into /iredadmin only the postmaster account is listed there.

I'm almost certain that I would have selected MySQL backend for mail accounts when I installed iRedAdmin, as I have no idea what LDAP is. Looking at my original /iRedMail-x.y.z/config file, I can see the lines:
  export BACKEND_ORIG='MYSQL'
  export BACKEND='MYSQL'

Does that confirm that I did indeed choose MySQL for the backend?

I can't figure out what db or table contains this information. If query the tables in iredadmin db on the old server, I get:
+---------------------+
| Tables_in_iredadmin |
+---------------------+
| deleted_mailboxes   |
| log                 |
| sessions            |
| updatelog           |
+---------------------+

So I wouldn't have thought any of those would contain the mail accounts, domains, and aliases.

Thanks in Advance.
