Rollback / Downgrade of QlikView 12.20 or 12.10 to QlikView 11.20Article Number: 000049931 | Last Modified: 2018/09/19
Note at first:A simple rolleback (uninstall new version, re-install old version) is not supported, and will cause issues with the Qlik environment that Qlik Support cannot resolve easily.
We always recommend getting in touch with a Qlik Consultant or Qlik Partner to plan and execute upgrades and also potential rollbacks.
Four things need to be considered when planning a step back between 12.x and 11.20:
End of LifeQlikView 11.20 has reached End of Life. At the least, we would need to request that the latest available service release of QlikView 11.20 will be used to upgrade the system after a rollback.
QVPRThe QlikView Reposisitory (QVPR) cannot be downgraded. 11.20 cannot use the upgraded version of the QVPR.
A backup of the QVPR will be required to proceed. See How To: Restore QVPR From Backup
Any changes made to the system in the Management Console will be lost.
Service SettingsSome settings files have received new settings in 12.x. These settings files are not always replaced. Backups of these must be available from your previous version. See Backup and upgrade preperation on our online Help. If this was followed, all necessary data will be available.
User Objects and BookmarksWe cannot guarantee that shared objects will be maintained. A backup of the previous files may need to be necessary. At the least, if the .SHARED files have been converted to .TSHARED, they will need to be converted back. See How to convert between different QlikView shared file formats
- Obtain a backup of the QlikView QVPR.
- Obtain backups taken before the original upgrade (.pgo files, .shared files, setting files).
- Uninstall QlikView.
- Backup the current, upgraded QVPR.
- Replace the current, upgraded, QVPR with the backup taken from before the upgrade.
- Replace all other available backup files. This includes setting files, .shared files, pgo files.
- Install 11.20.
