Pre-stage the Code42 app upgrade (CrashPlan)


By default, upgrading devices in the Code42 cloud involves sending upgrade files to each user device when the device connects to the Code42 cloud at the scheduled update time. Depending on your environment, this process can consume enough network bandwidth that it results in slower network speeds during your employees' working hours.

To alleviate this problem, if you have already set an upgrade delay, you can optionally pre-stage the Code42 app upgrade files on each device during off-peak hours using a client management tool like SCCM or JAMF. Then when upgrade occurs, the upgrade files are already in place on each device, resulting in faster upgrade performance.


Perform this procedure before initiating client upgrades.

That is, pre-stage the upgrade files before the date shown in the Scheduled Update setting, or if you choose to manually update clients ahead of schedule, before you select Upgrade Clients.


Step 1: Download the upgrade .jar files

To obtain the Code42 app upgrade .jar files to distribute to devices, click the links below to immediately start downloading. Choose all the operating systems for devices in your Code42 environment.

The files all have the same name, so download them per operating system to separate locations to help identification and to avoid accidentally overwriting one another.

Step 2: Pre-stage the upgrade .jar files

  1. Push the .jar files using your preferred file management application and place them in the Code42 app /upgrade directory on user devices.
  • Upgrade from 8.2.0 or later
    If you're upgrading from Code42 app version 8.2.0 or later, and the Code42 app is installed for all users, place the .jar files in the following directories:
    • Windows: C:\Program Files\Code42\upgrade
    • Mac: /Library/Application Support/CrashPlan/upgrade
    • Linux: /usr/local/code42/upgrade 
  • Upgrade from 8.0.0 and earlier
    If you're upgrading from Code42 app version 8.0.0 and earlier, and the Code42 app is installed for all users, place the .jar files in the following directories:
    • Windows: C:\Program Files\Crashplan\upgrade
    • Mac: /Library/Application Support/CrashPlan/upgrade
    • Linux: /usr/local/crashplan/upgrade
Code42 app installation paths
Use the above paths if the Code42 app is installed for all users (the default). If the Code42 app is installed per user, see the CrashPlan file and folder hierarchy for the application location under which the /upgrade directory can be found. 
  1. Select Administration > Client Management > Updates to schedule client updates.
    On the date of the Scheduled Update on the Client Updates screen, Code42 upgrades clients in your environment using the upgrade .jar files pushed to the devices.
