Troubleshooting The Upgrade From Version 4.1.6 To Version

Applies to:
  • CrashPlan PROe


If you have trouble upgrading your Code42 environment to version, these tips can help you troubleshoot the problem.

If you have any concerns about the upgrade process, stop all upgrade operations and contact our Customer Champions for assistance.

Troubleshooting your Master Server upgrade

What if the Master server upgrade fails?

If your master server upgrade fails, your master 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

Error processing upgrade: INVALID_FILE - Unable to read properties,

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

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 installation files instead of upgrade files

To resolve this error:

  1. Stop the enterprise server service.
  2. Navigate to the enterprise 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
    • OS X: /Applications/
  3. Remove all files from the /upgrade folder.
  4. Download the upgrade file (not an installation file) from the location provided in the upgrade instructions.
  5. Place the upgrade file in the /upgrade folder as described in the upgrade instructions.
  6. Start the enterprise server service.
  7. Apply the upgrade as described in the upgrade instructions.

Cause: Insufficient space in your multi-server deployment

Another common cause is a server in a mulit-server environment running low on storage space.

To resolve this error:

  1. From the administration console, check the available storage space on each of your storage servers.
  2. If possible, add storage space or reclaim storage space in use.

Administration console inaccessible after upgrade

Windows-based Code42 servers only

In certain circumstances, the administration console may be inaccessible after a Windows Code42 server is upgraded. This issue occurs when necessary files are locked by the operating system during the upgrade process, and is most commonly experienced on Windows servers that do not meet the system requirements for Code42 servers. The upgrade will succeed when Windows releases the locked files.

To resolve the issue, attempt the upgrade again on the affected Code42 server:

  1. Uninstall the newer version of the Code42 server.
  2. Install the older version of the Code42 server.
  3. Import the database dump you made before attempting the upgrade.
  4. Perform the upgrade to the newer version of the Code42 server.
