How much time do you have, Gary? If you have several months to play with I'd hold off and dig as late as you can it's a lot easier to transport just roots. If you need them moved in the next month or 2 I'd go for the grow bags and just store them in shade until fall. I actually had to dig up several roots that I missed on the land we're selling and all are in grow bags under a huge pine, they seem to be doing fine.
