Rollback in Case of Failed Upgrade

If a Control Center upgrade fails, here is how to return the system to its state immediately before the upgrade:

• Make a clean Ubuntu installation according to the Installation Guide, chapter Installing Required OS and Software.
• Install the version of Control Center that you were using before the upgrade. Again, follow the Installation Guide, chapter Installing Control Center and Related Tasks.
• Recover your data from backup as explained in the Operations Guide, chapter Restoring Product Data from Backup.
