ABSTRACT:
In one aspect, a method to convert a logical unit from a first encryption state to a second encryption state includes receiving a request to convert a logical unit from a first encryption state to a second encryption state, partitioning the logical unit into areas comprising a converted area, an unconverted area and a transition area, writing unconverted data in the transition area to a journal, converting the unconverted data from the first encryption state to the second encryption state and writing the converted data to the logical unit.
