* Catalogue all applications active in the current ownCloud instance. Take special care to identify the "core" applications that were activated and third party applications that were installed. There is no guarantee that third party applications will work on a new ownCloud release.
* Review and document all ownCloud sharing techniques used in the current ownCloud instance.
* It is recommended that all third party applications be disabled before upgrading.
* Do backups of the ownCloud database, binaries and stored files.
* Go to the Amahi Dashboard, Apps => Installed, and uninstall the current ownCloud instance. This will remove the ownCloud binaries and ownCloud database.
