Eric,

That list looks good, except:

/etc/spamassassin should be /etc/mail/spamassassin, unless it's different on CentOS7.

I'm unsure as to the MariaDB admin password on the current machine as my predecessor set it up.

I will poke around my docs and see if I can find anything. And, I didn't realize rsync was not in default install in minimal. Weird.

Thanks again, Eric, this is very helpful.  Everybody here is the best.

Hi Sean,

Off the top of my head I do the following:

On the QMT/COS7 Install make the MariaDB admin password the same as on your old machine.

1) Install rsync on both machines

2) Make ssh work without password

# How to make the below rsync ssh command work without a password
# exec ssh-agent bash
# ssh-keygen
# ssh-copy-id 'new server ip'
# ssh 'new server ip'

3) I rsync the CONTENTS of the following folders, old server to new

/var/lib/squirrelmail/prefs
/usr/share/spamassassin
/etc/spamassassin
/etc/tcprules.d
/var/qmail/control
/var/qmail/users
/home/vpopmail/domains

rsync --progress --delete -var -e ssh ${folder}/ $REMOTEUSER@$REMOTEHOST:${folder}

4) Dump vpopmail mysql database on old server and restore on new.

At this point you should be able to connect to the new server from mail clients.

5) Secure qmailadmin and vqadmin /etc/httpd/conf/toaster.conf for CentOS 7 ( http://www.qmailtoaster.com/notes.html)

Hope I'm not forgetting anything.


Eric

Good day all,

I've finally acquired a "new" machine to house our current install of the toaster, installed CentOS 7 and ran all available updates, and rounded up the preparatory files for the install. I will most likely install qmailtoaster and take it on a test drive before migrating our current install to the new box. I would like to inquire on the best way to do this, since the current install is on a CentOS 5 box and we are running Courier instead of Dovecot. Should I restore from a backup, or should I recreate the domain on the new box? I'm in no hurry, the current install is performing like a champ, and I have a backup machine in place should something go awry before the new machine is ready. Any advice or horror stories would be greatly appreciated.

Thanks!

-Sean
