1) Migration to new host

a) On destination host Install QMT/CentOS 7, instructions here. toaststat (make sure all services are running)

b) On source [cdb] host dhost=192.168.1.3 (change destination [mysql] host to suit) ssh-keygen ssh-copy-id $dhost ssh $dhost (test, no password should be required)

  1. The first rsync migrates the bulk of the email database with vpasswd files except those queued during sync

rsync --progress -zv -are ssh /home/vpopmail/domains/ root@$dhost:/home/vpopmail/domains

  1. Stop qmail/dovecot on source host and destination hosts

qmailctl stop && systemctl stop dovecot

  1. The second rsync, services stopped, migrates the balance of the email database
  2. and control files

rsync --progress -zv -are ssh /home/vpopmail/domains/ root@$dhost:/home/vpopmail/domains rsync --progress -zv -are ssh /var/qmail/control/ root@$dhost:/var/qmail/control rsync --progress -zv -are ssh /var/qmail/users/ root@$dhost:/var/qmail/users rsync --progress -zv -are ssh /etc/tcprules.d/ root@$dhost:/etc/tcprules.d rsync --progress -zv -are ssh /etc/dovecot/toaster.conf root@$dhost:/etc/dovecot rsync --progress -zv -are ssh /etc/dovecot/local.conf root@$dhost:/etc/dovecot

  1. Not necessary to the migration

rsync --progress -zv -are ssh /usr/share/toaster/include/admin.pass root@$dhost:/usr/share/toaster/include rsync --progress -zv -are ssh /usr/share/toaster/include/admin.htpasswd root@$dhost:/usr/share/toaster/include rsync --progress -zv -are ssh /usr/share/squirrelmail/plugins/ root@$dhost:/usr/share/squirrelmail/plugins rsync --progress -zv -are ssh /etc/spamassassin/.spamassassin/ root@$dhost:/etc/spamassassin/.spamassassin rsync --progress -zv -are ssh /etc/spamassassin/local.cf root@$dhost:/etc/spamassassin rsync --progress -zv -are ssh /var/lib/squirrelmail/prefs/ root@$dhost:/var/lib/squirrelmail/prefs

c) On destination host

  1. Convert vpasswd files to mysql vpopmail db, aliases must be handled manually

/home/vpopmail/bin/vconvert -c -m qmailctl cdb && qmailctl start && sleep 2s && systemctl start dovecot && toaststat



2) In place conversion*

  1. qmailctl stop && systemctl stop dovecot
  2. yum install -y yum-utils
  3. yum-config-manager --enable qmt-current
  4. yum reinstall qmail qmailadmin dovecot* ezmlm* vpopmail vqadmin
  5. /home/vpopmail/bin/vconvert -c -m
  6. qmailctl start && sleep 2s && systemctl start dovecot && toaststat
  • Aliases must be done manually.
 Will convert to many domain format if 
 vpopamil was compiled with this option
