- The Aspera Enterprise Server installer automatically checks for an
older version of the product on your system. If an older version is found, the
installer automatically removes it before installing the new version.
- Although the installer performs your upgrade automatically, Aspera highly
recommends completing the tasks below before upgrading. If you do not follow
these steps, you risk installation errors or losing your former configuration
- You cannot upgrade directly between different Aspera transfer products (such as
from Point-to-Point to Desktop Client, or from Point-to-Point to Enterprise
Server). To upgrade, you need to back up the configuration, uninstall the
product, and perform a fresh install of the new version of the product.
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.
- With a backup: Follow the steps below to prepare your machine. Uninstall the
application (for instructions, see Uninstalling).
Copy the older Redis DB file into the var directory before
installing the older (downgrade) version.
- Without a backup: Follow the steps below to prepare your machine.
Uninstall the application (for instructions, see Uninstalling) and delete the var
and etc directories from your machine. Then do a fresh
installation of the older version. The configuration files in the
etc directory may be compatible with older versions,
but not all configurations may be read.
