* Navigate to Restore the Apps page.* Compare the list of third party party that were used in the previous ownCloud instance with the third party applications available in the newly installed release.* If all the third party applications match then restore the applications from backups.* If there is no match for the third party applications; activate the "core" applications needed, enable the third party applications needed. Please remember applications not available will take time for the third party authors to update for the new release version.* Enable required "core" and third party applications "one-at-a-time", testing each application. Stop at any behavior that is not the same, this usually happens with third party applications.
