Tested on Linux CentOS 6.x and 7.x with Zimbra FOSS 8.8.15

In this tutorial we will demonstrate how you can install the latest patch on your Zimbra Open Source Collaboration Server 8.8.15.

Pre-requisites

1. You have root ssh access on the server. If you don’t have contact your hosting provider,
2. Take full backup of your server. If you are using NetShop ISP Cloud VPS request a snapshot by submitting a ticket to support@netshop-isp.com.cy. If you are using Dedicated Servers please check our Backup plans here.

Zimbra Upgrade Steps

As root, first clear the yum cache and check for updates. This is so that the server can see there is a new zimbra-patch package in the repositories.

Type the following commands and hit enter:

yum clean metadata
yum check-update

Then, ask yum to update the available packages by issuing the following command:

yum -y update

Now, restart Zimbra as a zimbra user:

su - zimbra
zmcontrol restart

Now, we confirm our Zimbra has been upgraded to the latest patch version.

As a zimbra user, issue the command:

su zimbra
zmcontrol -v

This is it! Enjoy your updated Zimbra!
