I actually replanted a seed and its doing fine. I looked around on the net too and a lot of people say it's ok but its a delicate procedure. One thing they stressed was keeping the root ball intact and be very gentle with it because the roots are fragile. They explained it like to wet the soil a little and then turn the plant upside down and tap the pot against a counter and it should come out of the pot all intact with the soil still in the shape of the original pot it was in. They also said it may cause it to stop growing for a period of around 2 or 3 days because the plant is trying to deal with the stress of being repotted.

Anyways thats what I read maybe someone cause answer it better than I can and may be able to tell you some no no's when replanting. Anyways if you decide to do it good luck. Hope it works out for ya.
