In April 2025, MassHealth will migrate its Medicaid Management Information System (MMIS) base application and Provider Online Service Center (POSC) to an Amazon Web Services (AWS) data center. MassHealth has published All Provider Bulletin 401- MMIS POSC Migration to Amazon Web Services, which outlines key cutover information. All published bulletins can be found on Mass.gov

- Reasons for Migration: Understanding the benefits of transitioning to AWS.
- Timeline of Activities: Key steps along with dates and times you need to be aware of.
