The update package that includes update commands is adapted for updating an original version of content to an updated version. The updating is carried out in accordance with an update sequence. The method includes determining direction of the updating. If the direction is indicative of forward then the method forward-updates the stored version to the updated version in accordance with the update sequence. If the direction is indicative of roll-back, the method generates a roll-back update sequence opposite to the update sequence and rolls-back the stored version to the original version in accordance with the roll-back update sequence.
