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.

All storage servers in your Code42 environment must use the same Code42 server software version as your authority server. 


  • If the File Selection setting is locked in the administration console (Settings > Device Backup > Backup), you must take action to ensure all Code42 app devices are using version 4.5.2 or later before upgrading to Code42 server version 5.3.
  • Beginning with version 5.3.0 of the Code42 platform, the Code42 app is no longer bundled with the Code42 server. Compatible Code42 app versions are available for download from the new App Downloads screen in the administration console. See Adding Clients To Your Code42 environment for more details.
  • Do not make any configuration changes to Code42 for Enterprise settings in the administration console while upgrading your Code42 server. As a best practice, wait 24 hours after pushing any configuration changes to Code42 for Enterprise apps before you upgrade the Code42 server, and wait 24 hours after the server upgrade completes before changing any settings. Contact our Customer Champions for Code42 for Enterprise support if you have any questions.

  • After the Code42 server upgrade completes, you may need to refresh the administration console to see the new App Downloads screen.
  • Depending on your browser's cache settings, you may be prompted to upgrade clients after the Code42 server upgrade completes. Ignore this prompt; client upgrades are managed from the new App Downloads screen beginning in version 5.3.
  • In Code42 environments that initially deployed version 5.x Code42 apps to user devices (and never upgraded devices from version 4.x to 5.x), you must follow the steps in Upgrading The Code42 app To Version 5.x to enable upgrades to Code42 app version 5.3.
