    Just wondering what procedure is recommended or how people manage the OS upgrades ?
    We have two VM's running CentOS 7.3, ISPConfig 3.1.7p1 with Master Master, sync email, unison www.
    With this type of setup is it best to disable all synchronization and then upgrade each OS ?
    Do people stop synch upgrade slave then upgrade master then restart sync ?
    Just curious as I haven't seen this covered in terms of recommendations

    In this setup you sync just /var/www and /var/vmail I guess, these directories should not be affected by an OS update, so you can leave the sync on in my opinion.
