Transition refers to the activities that will be undertaken by the Programme and by Programme participants to move from the Legacy arrangements to the new MHHS arrangements and the new Target Operating Model (TOM), while Migration refers to the process by which Meter Point Administration Numbers (MPANs) are migrated from the Legacy arrangements to the new MHHS arrangements.  

The Migration, Cutover and Data Strategy document sets out the strategy and approach that the MHHS Programme will follow to develop a suite of policies, processes and other Artefacts to support both Migration and Cutover and Data Cleansing activities. 

The Data Cleanse Plan details the data cleansing and population activities required to ensure that data is of the required quality and completeness ahead of the MHHS Migration.
