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. If you have more than one enterprise server, upgrade the master server first.

Most enterprise 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.

Wait at least 24 hours before upgrading
If you recently upgraded to version 4.2.x from an earlier version, wait 24 hours after upgrading your authority server and all storage servers before upgrading to another version. This waiting period ensures that all post-upgrade migration processes are complete before you start another upgrade.

Upgrading your devices

Devices with the CrashPlan app or SharePlan app upgrade automatically once you enable the device upgrade. We recommend testing the upgrade on a single CrashPlan 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 master server before your devices can upgrade. When the master server has restarted, devices reconnect to the upgraded master server at a randomized interval of 1–15 minutes. Devices download their upgrades from the master server over TCP port 4280 and upgrade themselves automatically. The randomized re-connect interval means that after the master server comes back online, there may be a delay before all devices have successfully upgraded.

Upgrading your mobile devices

Mobile devices do not automatically upgrade from the authority server. Depending on your environment, either:

  • Instruct your users to update the CrashPlan mobile app or SharePlan mobile app from their devices' app store.
  • Configure your mobile device management tool to push an upgrade to your managed devices.
