No problem.
I speak hydro.

Get a 5 gallon bucket with a lid.
Cut a hole in the lid to accommodate your plants container.
Leave the dirt in the container
Fill the bucket with nuted water to about 2 inches from the bottom of your container and drop in an airstone.

The bubbles will splash the bottom and the roots will descend into the bucket.
No transplant shock at all.
