'''Upgrade'''
Upgrade is to bring an ownCloud instance to a new major release, (ownCloud 4.5.6 → 5.0.0). Always do backups anyway.To upgrade ownCloud, follow those steps:
• Make sure that you ran the latest point release of the major ownCloud version, e.g. 4.0.x in the 4.5.x series. If not, update to that version first (see above).
