Kestrel

The Migration Planning and Management Tool (MPMT), also known as Kestrel, is built around a role-based framework to support the planning, management, and reporting of MHHS migration data. The tool ensures that all market participants can access the planning functionality and insights they need whilst safeguarding commercially sensitive information.
