Another couple of questions…since most of my HSA funds are invested (Optum, in Vanguard funds) does it have to be converted to cash before transfer? Can investments transfer? If not, am I taxed at all when rolling over? If must liquidate first, I assume that I can re-invest once with Fidelity. Finally, do I initiate this from Fidelity side? Wait until I separate from service? Or have some people done partial transfers?
