I'd do it once the leaves have fallen. Prepare the site well and when you dig them take as large a rootball as possible. Lift the rootball and slide it onto a sheet of plastic or binbag and drag it to the new site to keep the soil around the rootball as intact as possible.
I'd try to do it without cutting back the branches, but you may need to shorten them a bit and tie them up to make it easier to handle.
Water in and mulch with leafmould and it should be fine.
