Migration Design

Here you can find the baselined Migration Design Artefacts.

The Artefacts below articulate the technical process through which Meter Point Administration Numbers (MPANs) will be migrated from legacy arrangements to the new MHHS arrangements, and in the case of Reverse Migration, back to the legacy arrangements from MHHS arrangements.

 

Migration Design Artefacts Baselined

The Migration Design Artefacts were baselined following approval at the extraordinary Design Advisory Group (DAG), on 31 March 2023. 

Since then, the Programme has processed Design Issue Notifications (DINs) raised by Programme participants. These are published in the Design Issue Notification (DIN) Log, published on the Design Review Process page of this website.

Following review of the DIN Log by the Design Team, several Design Artefacts are being updated with red-lined changes for participant review. The Programme is publishing the Red-lined Design Artefacts through six Interim Releases, following the Design Review Process.  

The Red-lined Design Artefacts and accompanying Release Notes can be found on the Red-lined Design Artefacts page of this website.

The Migration Design was created in collaboration with industry through the Migration Design Subgroup (MDSG).
