    Default [SOLVED] RedHat5_64 OS update

    I am looking to do a OS update in preperation of going to ZCS 6. Is it as simple as yum update? Do I need to stop the Zimbra services beforehand?

    Thanks

    I would suggest you block email from coming in to your server, disable Zimbra from starting at boot, take a full NE backup, stop Zimbra then backup the /opt/zimbra directory (use rsync) and move the backup to another machine - when you've done that run 'yum update'. When the update is finished reboot the server and start Zimbra manually, make sure it's working OK and set zimbra to start at boot then allow mail through the firewall.

    Thank you for your response. Just a quick followup, what are the possible issues if I am unable to block messages from coming in? Mail for several other servers come into the same relay so I cannot block at the firewall.

    There should be no problem other than if you have any problem restarting after the upgrade and have to do restore then you may lose some mail. The likelihood of problems is minimal but obviously you should always prepare for the worst.

    Thanks again. I am running into one last hurdle. My opt/zimbra directory is too large to move to another server. Am I most likely safe if my /opt/zimbra directory is on a msa that is attached via fiber to the server?

    Yes, that should be OK.
