Before Upgrading or Downgrading



Older installers do not check for newer versions of the application. You must prepare your machine as described below then uninstall the newer version before continuing with your downgrade.

Newer versions of the Redis database are not compatible with older versions of the application. Your downgrade process depends on whether a backup of the older Redis DB is available, either as a separate backup file or as part of your backup of the var directory from the older version.

Preparing for an Upgrade or Downgrade

  1. Verify the version of your existing product.
    The steps required to prepare for an upgrade may differ depending on your current product version. To view the current product and version, run the following command:
    # ascp -A
  2. Stop all FASP transfer-related applications, services and connections.
    • ascp connections
    • The Desktop Client application
  3. Back up configuration and settings files.
    These files are found in the etc and var folders.
    • /opt/aspera/etc/ (contains server configuration, web configuration, user settings, license info)
    • /opt/aspera/var/ (contains Pre- and Post-Processing scripts, Connect Server)
