It's usually not a good idea to replant unless the plant needs it to stay healthy. What is the orchid planted in as far as soil type. Mine are in orchid potting soil or in another words small bark pieces. They like to be misted several times a week. And there is a special orchid food that you can get for them. Also the roots need to breath so you need to have the humidity tray situated in such a manner that the drain holes are not sitting in water. I have a wrought iron candle holder sitting in my humidity tray that my pot sits on. It looks kind of cute, I think anyway.

My orchid also have a rough sided piece of wood situated close to them so that if they need to put roots into something it can be that rather than my drywall/plaster lol.

Orchids don't like wet feet that's another thing I've learned so far. but I just got my orchids about a month or so ago. So I'm sure you'll get more good information soon from others.
