Just like Ron said. Move em' before they fry. They are going into a shdy spot, right? Move em' and water them well. Most plants move easier than most imagine. Just do it right....and soon.

if you are realy worried about transplanting in the heat but it Must be moved, you can pot the things up as tenderly and carefully and quickly as you can, then put them in a sort of holding area till the cooler weather comes, or till the plants recover from being moved. I would set them in dappled shade, or morning sun,. in saucers, or grouped in shallow tubs, I have those black plastic cement mixing trays on hand for this type of thing, or even a very shallow kiddy pool will work, or you can knock together a sort of tray by making a square of 2x4's lined with plastic, then you can give the stuff a good drink easily for a few days, Not setting in water, but easy to water all at once. this will buy you some time to think what to do next.
