2022.1

Note that an erroneous or incomplete uninstall before a reinstall or upgrade to a newer version
of OL Connect may cause issues (see Product or engine exits within a second of starting in
Connect's Knowledge Base).
Note
If an error occurs during uninstallation or after/when re-installing Connect after
uninstalling it, please see: Problems during a Connect installation or version upgrade in
Connect's Knowledge Base (https://help.objectiflune.com/en/kb-
connect/#KB/FAQ/General/Installation_Upgrade.htm).
Backup existing Connect version
It is recommended that you always backup your existing Connect preferences before upgrading
to a new version. This will enable you to revert back to the previous version, in a worst case
scenario in which the new version introduces issues with your existing production processes.
Whilst the probability of such a worst case scenario is remote, it cannot hurt to take some
simple precautions, just in case.
Backing up a virtual machine
Backing up a virtual machine installation is relatively straight forward. Simply take a snapshot
of the virtual machine instance, prior to upgrading. This would save all the localized
preferences and configurations.
Backing up a real machine
Note
The scheduling settings in version 2019.2 have totally changed, making it impossible to
revert these settings back to the previous version. Please make sure to record your
current Scheduling settings for reference before proceeding with an upgrade.
