When I said down pot I meant that you need to move it to a smaller size, not do a repot. You need to slide the soil carefully out of the pot and remove some on the sides and bottom to fit into smaller pot. It is best not to disturb the roots (if Amy are left) at this point. If a lot of soil drops off loosely when you remove it , just try to keep as much as possible together near center where the roots should be. If all soil just falls out you probably should see if any roots are visible around the stem or not. Try not to disturb them. Just slide it sideways into the new pot and fill a little on sides if it fell out.
And don't pull it by the stem or hold it by the stem: when roots are small it's very easy to break them off. Small long scoop for planting would help to move the stem out with some soil around it.
