If you want to upgrade your ZXTM Appliance from version 4.0, please see the
4.0 upgrade instructions.

Upgrades between minor versions

Upgrading between minor versions (e.g. 4.1 to 4.1r1) is very quick and simple:

• Download the upgrade package from your customer page.
• Log into the Administration interface, and go to the System -> Upgrade page.
• Upload the upgrade package, and follow the instructions.

You will need to complete this process for each Appliance in your cluster.

Expected downtime for an upgrade will be a couple of seconds while the Traffic Management software is restarted. Sometimes it will be necessary to reboot the Appliance to complete the upgrade. The user interface will inform you if this is necessary when the upgrade is complete. You should ensure that the Appliance is rebooted at the most appropriate time.
