Can I switch plants in soil to a hydro table?

I have a bunch of small plants in small cups that are growing in canna-coconut stuff. The roots structures are still small and compact. Can I rinse the coconut shit off of the roots and put them onto an ebb and flow hydro table setup that was recently given to me? As long as I can get the rootballs into large rockwool cubes gently I wouldn't see it being a problem. Any suggestions u could give would be great.
