Upgrade your single-server Code42 environment

Applies to:
  • Code42 for Enterprise


This article describes how to upgrade your single-server Code42 environment to a new Code42 server version.

For multi-server environments, see Upgrade your multi-server Code42 environment.

Managed authority server upgrades
If your authority server is managed or monitored by Code42, our Customer Champions work with you to upgrade your Code42 environment. Do not attempt to upgrade your environment on your own.


  • When you apply the upgrade, the Code42 server service shuts down and performs the upgrade tasks. When the upgrade tasks are complete, the Code42 server service starts up automatically.
  • Most Code42 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.

Before you begin

To avoid security risks, keep your operating system updated.

  1. Download the upgrade files for your host server's operating system:
    1. Find the upgrade instructions for your version.
    2. Near the bottom of the instructions, locate and click the appropriate download link.
  2. From the administration console Subscriptions screen, verify that your Code42 environment licenses are valid and up-to-date.
  3. Make sure that your host server meets the Code42 server requirements.
Test the upgrade
We strongly recommend that you perform the following upgrade steps in a test Code42 environment before upgrading your production Code42 environment.

Step 1: Prepare your Code42 environment

  1. Sign in to your Code42 server's administration console.
  2. Dump your Code42 server's database:
    1. Navigate to Settings > Server.
    2. From the action menu, select Dump Database.
  3. Verify that the database dump was successful:
    1. From the action menu, select Import Database.
      You see a list of dump files identified by timestamps in their filenames. 
    2. Find the file with the current date and time that ends in .sql.gz. This indicates that the database dump completed successfully.
      • If the file extension ends in .sql, database dumps aren’t completing successfully. Contact our Customer Champions for Code42 for Enterprise support. We strongly recommend that you do not upgrade your Code42 server until you have a current database dump file.
      • If you don't see a new dump file, click Cancel, wait 10 seconds and then select Import Database again.
    3. When the new dump file is present, click Cancel (not Submit).
  4. In Settings > Server, disable Auto-upgrade devices.

Step 2: Upgrade your Code42 server

  1. Sign in to the administration console of your Code42 server.
  2. Navigate to Settings > Server.
  3. From the action menu, select Upgrade.
  4. Locate and select the upgrade file.
  5. Review the End User License Agreement and click I AGREE to proceed with the upgrade.
    The Code42 server restarts after successfully upgrading.
  6. Clear your browser cache to ensure that you access the new version of the administration console the next time you connect.
  7. After the Code42 server restarts, sign in to the administration console.
    The message Server Upgrade Complete appears.
  8. When prompted, click No, I'll Upgrade Later to postpone upgrading all client devices.
  9. Verify the following:
    • Under Settings > Server, the Current server version displays the new Code42 server version.
    • You are able to view the details of any organization, any user, and any device.
    • User devices are able to reconnect, back up, and restore.

Next steps

If the new Code42 server version introduced a new Code42 app version, upgrade the Code42 apps in your Code42 environment.

Troubleshooting the upgrade

Authority server does not successfully upgrade

If your authority server upgrade fails, your authority server is still recoverable. The internal database is protected during upgrades, which allows our Customer Champions to restore the server to working order.

As soon you notice a problem, stop upgrading immediately and contact our Customer Champions for Code42 for Enterprise support.

Error: Invalid_file or unable to read properties

If the administration console or log viewer displays the following error message after attempting to upgrade your Code42 server, there are several possible causes.

Error processing upgrade: INVALID_FILE - Unable to read properties,

Cause: Invalid upgrade file

One common cause is using an invalid upgrade file, such as:

  • Using a corrupt upgrade file
  • Using an upgrade file for the wrong version
  • Using an installation file instead of an upgrade file

To resolve this error:

  1. Stop the Code42 server service.
  2. Navigate to the Code42 server /upgrade folder on your file system:
    • Linux: /opt/proserver/upgrade
      Applies to Code42 servers installed as root on Ubuntu
    • Windows: C:\Program Files\CrashPlan PROe Server\upgrade
  3. Remove all files from the /upgrade folder.
  4. Start the Code42 server service.
  5. Download the upgrade file (not an installation file):
    1. Find the upgrade instructions for your version.
    2. Locate and click the appropriate download link.
  6. Apply the upgrade as described in the upgrade instructions above.

Cause: Insufficient space on a Code42 server

Another common cause is a Code42 server running low on storage space.

To resolve this error:

  1. From the administration console, check the available storage space on your Code42 server(s).
  2. If possible, add storage space or reclaim storage space in use.
