Using your Linux package manager with our official ownCloud repositories. This is the recommended method.
With the Updater App (Server Edition only). Recommended for shared hosters, and for users who want an easy way to track different release channels. (It is not available and not supported on the Enterprise edition.)
Manually upgrading with the ownCloud .tar archive from owncloud.org/install/.
Manually upgrading is also an option for users on shared hosting; download and unpack the ownCloud tarball to your PC. Delete your existing ownCloud files, except data/ and config/ files, on your hosting account. Then transfer the new ownCloud files to your hosting account, again preserving your existing data/ and config/ files.
Enterprise customers will use their Enterprise software repositories to maintain their ownCloud servers, rather than the Open Build Service. Please see Installing & Upgrading ownCloud Enterprise Edition for more information. www.mcdvoice.com
