I also have a solo/individual 401K plan for my LLC (of which I’m the sole member and no employees). It was first opened it at Vanguard as a new plan and I gave it plan sequence number '001'. I then moved the plan to Fidelity, designated it as an 'amended plan, amended and restated from another plan document' and used plan sequence number '001'. Is that correct, or does an amendment or restatement require that the plan sequence number be incremented? Should I have given the plan the sequence number '002' when I moved it to Fidelity?
