Thanks for all the input. The leaves are certainly done now so it is mulched and watered and ready for winter.
My thinking was to have the last bit of active growth supportting new root development, but now I wonder should I have transplanted later? It was a big project to do by hand and from shade to sun it is difficult to expect much.
Do trees store up enough food to grow roots after leaf fall and still have reserves for spring?
Thanks for the websites, it is clear I should brush up on some botany
