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. Confirm your Aspera service account.
    The Aspera service account was created when you first installed IBM Aspera Enterprise Server, Connect Server, Point-to-Point Client or Desktop Client on your computer and you will need this account information during the upgrade. By default, the user name for the Aspera services account is svcAspera; however, this is not a requirement and you may have selected a different user to run the services.

    To identify which user is designated as your Aspera service account in Windows 7, click Control Panel > Administrative Tools > Services. In Windows 2008, go to the Server Manager and select Configuration > Services. Find the account associated with the Aspera services (such as ASpera Central) and record the username. If you have forgotten the Aspera service account password or would like to change the designated Aspera service account, follow the instructions described in Managing the Aspera Service Account.

  3. Stop all FASP transfer-related applications, services and connections.
    • ascp connections
    • The Desktop Client application
    • Aspera Sync service (the Aspera Hot Folder service)
  4. Back up configuration and settings files.
    These files are found in the etc and var folders. Their location depends on the version of your previous installation and the operating system.

    Aspera 2.5+

    • C:\Program Files[ (x86)]\Aspera\Client\etc\ (contains Configuration files, Shared Remote Hosts)

      > echo %APPDATA%
