What to expect

Upgrading your server

When you apply the upgrade, the enterprise server service shuts down and performs the upgrade tasks. When the upgrade tasks are complete, the enterprise server service starts up automatically.

Most server upgrades take 5-10 minutes to complete; however, upgrades in larger environments may take 15-30 minutes or more, depending on the size of the environment.

If you have more than one Code42 server, upgrade the authority server first.

Managed appliance Upgrades
If your authority server is a Code42 managed appliance, our Customer Champions work with you to upgrade your Code42 environment. Do not attempt to upgrade your environment on your own.

Upgrading your devices

Devices with the Code42 app or SharePlan app upgrade automatically once you enable the device upgrade. We recommend testing the upgrade on a single Code42 app or SharePlan app device before enabling automatic upgrades for all of your devices. Please review Best Practices for Upgrading Your Devices prior to upgrading.

Once you enable device auto-upgrade, you must restart your authority server before your devices can upgrade. When the authority server has restarted, devices reconnect to the upgraded authority server at a randomized interval of 1–15 minutes. Devices download their upgrades from the authority server over TCP port 4280 and upgrade themselves automatically. The randomized re-connect interval means that after the authority server comes back online, there may be a delay before all devices have successfully upgraded.
