I have a client with a prevailing wage plan that was on a GUST standardized Money Purchase Plan document and is getting merged into a 401(k) Volume Submitter Plan. Is it necessary to restate the prevailing wage Plan for EGTRRA prior to the merger or can I complete the participation Agreement indicating "Restatement and Merger" on the Corbel volume submitter 401(k) document?

I have a client who sponsors a multiple employer 401(k) Plan and has 3 other 401(k) Plans that are going to be merged into the multiple employer plan. Can I just merge the 3 plans and complete the participation Agreement indicating "Restatement and Merger" on the Corbel volume submitter 401(k) document?
