Glenn, how long have they been in position? I ask only because if they are well established I would wait until September. They will still survive but summer heat will take its toll so lots of water for a week or two then make sure they don't dry out. Recently planted means they will move just fine now
however, I move them regardless of time of year and they are fine.
They will have large, deep and heavy root systems so be prepared for a generous dig. Prepare a recipient hole and make it large. Plenty of organic matter.....mushroom compost is prob the best....and fish blood and bone fertiliser. At least dappled shade too if you can
