Transition
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.
The MHHS Service Management Strategy document defines the strategy which will underpin the management of the new MHHS services.
The Service Definition Document (SDD) defines the key support processes relating to the delivery of MHHS at a high-level. The document serves as a reference point for both Service Users and Service Partners, providing a high-level view of how Elexon will support new services.
The Low-Level Service Definition Document (LLSD) relating to Target Operating Model (TOM) Service Users defines the key support processes and integration with Elexon’s Service Portal relating to the delivery of MHHS. It covers the required service management processes and procedures used by Elexon Service Providers and Service Users based on current ITIL v4 best practice.
The M10/M11 Cutover Plan sets out the activities that MHHS participants will be required to carry out in the lead up to M10, at M10, and between M10 and M11 to enable the Programme to successfully reach both M10 and M11 respectively.
Elexon has revised its approach to DTN File Numbering during Transition.
Service Activation is the process where following successful Qualification, participants are onboarded to Elexon’s new systems.
