Instructions
c) On destination host
# 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*
# qmailctl stop && systemctl stop dovecot
# yum install -y yum-utils
# yum-config-manager --enable qmt-current
# yum reinstall qmail qmailadmin dovecot* ezmlm* vpopmail vqadmin
# /home/vpopmail/bin/vconvert -c -m
# 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
