Our approach
We mapped legacy records to FHIR and HL7 standards, migrated in controlled stages with automated reconciliation, and kept systems running throughout.

-
Staged migration
Data moved in phases with reconciliation at each step.
-
Verification
Every migrated record checked before decommission.
