Prophet 21 users: Epicor just gave on-premises support a real end date. June 30, 2029.
Epicor announced this back in January, but it's still catching a lot of P21 users off guard. On-premises Prophet 21 gets one more feature release (version 2028.1, targeted for May 2028), then active support through June 30, 2029.
After that, it's sustaining support only, no security patches, no compliance updates, nothing new added to the system. It'll keep running. It just won't get any better while the risk keeps adding up in the background.
We put together a full breakdown: the actual timeline, who's affected (on-prem and self-hosted, not Epicor-managed cloud), and what's worth thinking through if a new ERP ends up on the table. Not a pitch, just what we'd want to know if we were running P21 today.
Full breakdown linked below, worth a read if P21 is running your business right now.
Here's the full breakdown:
