Those roots that you saw, despite that it's still healthy will be gone within a month, however, by that time, it will usually grow a new set of root and is ready to be transplanted into a new media. Make sure sanitize that plant clearly before putting them in water. Once they're in water, you don't have to lower the light, let them get as much light as they want, like where you usually put them. That way, they establish faster. And lower the water level so that it just over the root, make sure that it doesn't go below the root. Algae is your friend. Lots of advices here:
