Hi all, I would need advice to upgrade an old dual-server setup: 2 identical servers : ubuntu 14.04.5 LTS, bind, apache2, MySQL, pure-FTP, postfix, dovecot, roundcube MySQL master/master replication between the 2 servers data replication of /var via Unison for www vmail and roundcube config file Code: # Roots of the synchronization root = /var root = ssh://server2//var/ # Paths to synchronize path = www path = vmail path = lib/roundcube/plugins/ispconfig3_pass/config/config.inc.php.dist server1 is the main one using dbispconfig1 database server2 is the failover one using dbispconfig2 database A third server actually checks services via Monit and switch DNS entries for websites via the ISPConfig API Thanks to let me know if this way would be the correct one : - Backup MySQL, config files and datas as usually - Stop MySQL Slave role on 2 servers - Stop Unison cron job - server2 (failover) : run ispconfig_update.sh, expert mode - server1 (main) : run ispconfig_update.sh, expert mode - copy /usr/local/ispconfig/interface/lib/config.inc.php from server1 to server2 - restart MySQL Slave roles on 2 servers - restart Unison cron job Thanks in advance for your time.

I think, you leave cron and mysql active. The update just makes some changes to the database. Is there any reason, why you sync the roundcube-config? And i would not use unision to sync mail. Better switch to dsync + dovecot.
