Transplant from soil to hydro

A question from a fellow grower:

Can you take a plant started in soil and grow it in a hydro grow box ?

I’ve heard that you can use R/O water to carefully wash the dirt from the roots, and then put into the hydro system with extreme caution to not break the root system. Your plants will have to endure a little bit of shock, but within a week or two you should be good…

Again I haven’t done it, just what i’ve learned from way too much time researching various techniques.
