Long story short; I recently rolled over my Roth IRA from NW to vanguard and would like to reallocate the funds in the account. Right now it’s mostly in GWPAX but I made this year’s Roth contribution into VOO and VTI (after I rolled over) and would like to exchange the GWPAX for a cheaper index fund or ETF. There would be no withdrawals from the Roth of any kind. Has anyone done this before and are there any pitfalls you encountered?
