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.

Before you begin

  1. Review the general instructions at Upgrade Version 4.3.x To
  2. From the administration console Licensing screen, verify that your support is up-to-date.
    Only environments under current support and maintenance are able to upgrade.
  3. Make sure that your host server meets the enterprise server requirements.
  4. (OS X) If your host server is running Java 6, upgrade to Oracle Java Development Kit (JDK) 7.
  5. Verify that your devices can download the device upgrade files from your enterprise server.
    Depending on whether your enterprise server is configured to require SSL, devices connect on TCP 4285 (for HTTPS) or TCP 4280 (HTTP).
Test the upgrade
We strongly recommend that you perform the upgrade in a test Code42 environment before upgrading your production Code42 environment.

    • You are able to back up and restore, or sync and share, files from your devices.

    3. From the action menu, select Upgrade.
    4. Click Upgrade to upgrade the device.
      The upgrade command is sent to the device immediately and the device begins the upgrade process. When the upgrade is complete, the administration console displays a “success” message in the lower left corner.
  2. Verify the test device upgrade:
    1. Launch the CrashPlan app or SharePlan app on the device and verify the version number.
    2. Confirm that you are able to back up and restore, or sync and share, files from the test device.
  3. When you are ready to upgrade the rest of your Code42 environment's devices:
    1. Sign in to the master server's administration console.
    2. From Settings > Server, enable Auto-upgrade devices.
    3. Click Save.
