Operating system updates

Hello, is it ok to update the Operating system packages on a Zimbra server? My Ubuntu 16.04 notifies me of several security packages updates every time I log in via SSH.

I found this wiki page: https://wiki.zimbra.com/wiki/Best_Pract ... ge_Updates that, as far as I understood, says that it is safe to upgrade Zimbra packages and OS packages (since it tells to use yum update / apt-get dist-upgrade) after stopping all zimbra services except ldap and zmconfigd:

Code: Select all

zmcontrol stop
ldap start
zmconfigdctl start

That article does not tell you that it is safe to upgrade the underlying o/s on a Zimbra server, it merely state the "Best Practices" for doing that procedure. If you think it's 'safe' then take a look at some of the forum threads about failed upgrades and what you might need to do for a recovery.

It is never, IMO, a good idea to do any major upgrade of the underlying o/s unless it's a minor point release - if all you're doing is some odd packages then there is probably not going to be any glitches and I'm sure you have good backup/restore and disaster recovery procedures in place and tested before doing any upgrades like this.

BTW, I'm going to remove your duplicate thread on this topic.
