Hey, just wanted to chime in with some very recent experience rolling over a 401(k) to Vanguard. I had both a traditional 401(k) and a Roth 401(k) with Schwab. When I called Vanguard to initiate the roll-overs, they strongly recommend that if you're rolling over the traditional 401(k) you move all those funds to a traditional IRA to create a clean paper trail. Then, once the rollover funds have cleared, if you decide it's worth converting some from the traditional IRA to a Roth IRA, you can do that as a next move. (Although in your situation and mine, I would not take that second step to convert any from the traditional IRA to the Roth IRA.) By the way, calling Vanguard to initiate the rollover was a great way to do this. The Vanguard rep even conferenced in the Schwab rep so that instructions could be given directly between the financial institutions. Schwab still had to mail the checks to me and then I had to mail them to Vanguard, but that was no big deal.
