Migration Supplier Envelope & Plan Submission Round 2

Migration Submission 2 is now open!

On Wednesday 7 May 2025, the MHHS Programme issued migration envelopes and weekly submission templates to all Suppliers who have provided Primary and Secondary Migration contacts.

You can access the Migration supplier envelope and plan submission round 2 via the Migration Planning & Management Tool, Kestrel, which you can find out more about on the Kestrel page of this website.

As per the Baselined Migration Framework, all Suppliers are required to complete and submit their weekly migration plans via Kestrel by Friday 20 June 2025.

The MHHS Programme has published a guidance document to support participants in navigating Kestrel. You can access this on the Kestrel page of this website.

The Migration team will host some drop-in Q&A sessions to assist with any queries on the submission process. We'll issue invitations to participants for these in due course.

User Access & Management

Participants who have been nominated as Kestrel users should already have access through an active MHHS account.

If you don't have this, please request this by emailing the Programme Party Coordinator (PPC) team at PPC@mhhsprogramme.co.uk  

Please note: Any changes to user access must be coordinated through your organisation's designated User Manager, as identified in the Programme Participant Information Request (PPIR) that was issued in April 2025.

To request additions or removals, please email the Kestrel team at Kestrel@mhhsprogramme.co.uk with the subject line formatted as follows:

<Supplier MPID> - <Role> - <Request Type>

For example: ABCD - Supplier - New User Request

Early Access to Validation Feature

To support suppliers in testing the validity of their migration plans against the Framework, Kestrel has introduced a Validation feature that provides validation findings upon submission of migration plans.

Please note: The Validation feature is still under development, however, an early-access version is included in the release that was issued on Wednesday 7 May 2025. The full feature set including additional validation rules, messages, and user interface enhancements will be rolled out in the coming days.

The Promote Plan feature is currently disabled and will only be enabled once the Validation functionality is fully implemented.

Once the Promote Plan feature is released, users will need to re-upload and re-validate your migration plan before it can be nominated for use by the Migration Control Centre (MCC).

We appreciate your support in testing and familiarising yourself with the current functionality. We'll make further updates available as and when required.

If you have any questions or you need further assistance, please email the Kestrel team at Kestrel@mhhsprogramme.co.uk
