Before upgrading or downgrading
When upgrading or downgrading, the following preparation ensures a smooth process, minimal transfer disruption so that your original configuration is backed up in case of any problems.
Upgrading
- s
- The 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 runs your upgrade automatically, completing the tasks before upgrading. If you do not follow these steps, you might get installation errors or losing your former configuration settings.
- You cannot upgrade directly between different Aspera transfer products, such as from HSTS or HSTE. To upgrade, you need to back up the configuration, uninstall the product, and run a fresh installation of the new version of the product.
Downgrading
Older installers do not check for newer versions of the application. You must prepare your system as described, and 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 database 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 these steps to prepare your system. Uninstall the
application, for instructions, see Uninstalling. Copy the older Redis database file
into the var directory before installing the older (downgrade) version.
/Library/Aspera/var/
- Without a backup: Follow these steps to prepare your machine. Uninstall
the application, 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 might be compatible with
older versions, but not all configurations might be read.
