PEP - Auto Enrollment Requirement

Employer has been a participated  in a MEP for several years. Not an auto enrollment  plan

As of 1/1/2025 the plan will move to a PEP.

Does the move to a PEP trigger the Auto Enrollment requirement for 2025?  Or is the plan grandfathered since it was in place prior to the Auto Enrollment Requirement.

Getting different responses from recordkeeper and TPAs?

Thank you.

The PEP will be a new plan, so plan accordingly.  Even though a PEP is a type of MEP, it is a whole different type than traditional MEPs.
