Upgrade from CentOS 6 to CentOS 7

Desire to upgrade aging CentOS 6 vm to CentOS 7

  • SSL all the things
  • mediawiki current versions wanted newer PHP version
  • implement virtual domain / email accounts

Moving the email

Email on the current, soon to be old CentOS 6 server, host0.redacted.net, is in unix passwd Mbox format. The new CentOS 7 server, host1.redacted.net, is in Maildir format. dediserve0 has multiple ~ thirteen (13) email addresses in the Mbox by nature of the postfix main.cf mydestination configuration setting. I want them all into separate virtual mailboxes on dediserve1.

IMAP sync utilities
  • dsync - Dovecot's mailbox synchronization utility (is there a more official man page say at dovecot?)
  • imapsync on github with recent activity (four months)
Preparation for moving email
  • purge unneeded messages in folders
    • deleted-messages
    • spam
  • Create new maiboxes on new server
  • imapsync ...
  • Change MX records
  • imapsync again for a few days until MX record change propagates.
#!/bin/sh
# jha 1/24/2018
# getting ready for the big move! :-)
# Testing syntax...
#
# --justfolders         make the folders on remote but no msg sync
# --dry                 dry run (test)
#

imapsync        --host1 dediserve0.jhalbrecht.net --user1 sampson --password1 'poit' \
                --search1 'TO "sampson@jeffa.org"' \
                --host2 dediserve1.jhalbrecht.net --user2 sampson@jeffa.org--password2 'bonk' \
                --automap --delete1 --noexpungeaftereach

Software Considerations

Build bacula from source for compatibility with my bacula[-fd|-sd|-dir] server

groupadd useradd  -r -s /sbin/nologin -d /var/spool/bacula -M -c 'Bacula Backup System' bacula

groupadd -r bacula

[root@dediserve1 systemd]# systemctl cat bacula-fd
# /etc/systemd/system/bacula-fd.service

Wordpress and MediaWiki move
