Our product is constantly improving so each new version has a number of feature enhancements as well as issues resolved.
We spend a lot of time making sure that upgrades are painless however because of the large variety of configurations and environments, issues may occur. We recommend that you comply with the following best practice guidelines to minimize the risk of data loss and interruption of service.
Keep a backup copy
Always read the release notes
Always keep a backup copy to roll back to if the upgrade runs into problems. Read instructions on how to backup and restore
Be advised that we do not accept any liability for loss of data in case you don't have a valid backup to roll back to the previous version.
Always do one upgrade at a time and at the end check that everything works before running another update. Do not try to apply several upgrades one after the other without checking if the system is running at each step.
