HELP ASAP for party: Cooked in baking dish, moved to baking pans - how to reheat?

[OrangeCrush1]

I made sweet potatoes for work and had to move them to smaller baking pans because I can't reheat them in the small oven at work in the large baking dish. I originally cooked at 350 degrees for 50 minutes. At what temp do I reheat and how long? I also have to put the marshmallows on top. THANKS!
