I'm attempting to move iRedMail to a new server.  So far I've:
1. Loaded CentOS 7  (Server with GUI template)
2. Loaded iRedMail 0.9.8
3. Loaded iRedAdmin Pro 2.9.0

The current running server has exactly the same releases.  The next steps are to:

4. Copy /var/vmail/vmail1 to the new server using scp.
5. Copy databases to the new server using:
            mysql -u root -p [database] < [database].sql

My question is do I need to copy all 6 databases?  It seems that only the vmail database is required -- and maybe iredmail and iredapd.  But wouldn't it be better to use the fresh amavisd, roundcubemail and sogo databases on the new server?

Thanks,
Jack
