This message is for users of the PECOS AI application in the Production environment.

CMS is migrating PECOS AI from on-prem to CMS AWS cloud and scheduled to go-live on May 4^th, 2026.

The PECOS application will begin migrating its technical components to the CMS AWS cloud environment starting April 20, 2026. Migration is scheduled for completion on May 3, 2026, with the system going live in CMS AWS Cloud on May 4, 2026.

There will be no business logic change to the application as part of this migration so it should be a seamless transition for most users. If you experience any issues after May 4th, please create a SNOW ticket for assistance.

The PECOS system is expected to be down on May 2^nd & 3^rd as part of the maintenance window.

Thank you,
