As part of Michigan’s transition to the new STC|ONE immunization information system, MCIR will temporarily pause all HL7 onboarding activities beginning October 1, 2025. This temporary freeze is necessary to support a smooth migration to the new platform.
Key Information:
- Sites currently in the onboarding queue must complete MiHIN paperwork, connectivity setup, testing, and data quality review in the legacy MCIR production environment by September 30, 2025.
- Beginning October 1, 2025, pending and new HL7 registrations will be tracked, but will not proceed with testing or production until after the new system goes live. HL7 onboarding is expected to resume in early April 2026, following the successful launch of STC|ONE.
Action Needed for Providers and their Vendors:
- MCIR staff will reach out to registered onboarding sites to support completion of onboarding steps by September 30, 2025.
