This request is raised in order to manage the delivery of two separate projects under 1 programme named DC Exit.

The details of two projects managed as part of the programme are as follows:

- Gemini Migration (Re-platform is a separate Change proposal funded by National Grid Transmission – CP4550)

- Data Centre Exit (Shared Components) Delivery – CR has been raised in parallel to this CP (4869). Reference number for the CR is 4870

The purpose of the two projects is to migrate and host all components currently within Peterborough and Kettering Data centre to ‘Platform as a Service’ hosting solution. The reason these projects are being delivered separately is mainly due to the funding arrangements as GRP project will be funded by NG Transmission and the remainder of the systems / components will be dealt via an internal change.
