I believe I can do that with the crepe myrtles because they were in one
gallon pots. The japanese elm and the saphire dragon were in 5 gallon
pots. How would I dig up the bigger ones w/o shocking the roots?
Thanks in Advance!

they are probably rootbound. That means the roots are going round and
round from years in the pots and prevent proper growth. Cu dig them
up and give them a good root pruning so that they have a chance to
spread properly in the future. do it in the fall before they go dormant.
