Control Group with a Safe Harbor and a Non-Safe Harbor Plan

[Vlad401k]

Let's say there are 2 companies in a Control Group. One of them is Safe Harbor, the other one is not. What happens if they fail coverage on their own and must aggregate?

 

I understand that you generally cannot aggregate Safe Harbor and non-Safe Harbor plans, but what would be the way to run testing if this scenario were to happen?

In our case, we amended the non-SH plan to a SH plan... then aggregate for testing.  Didn't really affect anything since the non-SH plan was already planning to give contribution amounts that would meet the SH requirements.
