Hi that’s good news for you. If you put them together, please don’t keep separating them. Each time they’re together again, they have to sort out the hierarchy again. It can be stressful for them.
If you have some hours set aside, put them together in a neutral area with no hides, a big pile of hay and veg. Make sure you clean out their cage thoroughly (no lingering scent from either). If you see they’re doing fine after some hours, you can then transfer them to the newly cleaned cage. Bear in mind the dominance display etc may go on for a couple of weeks.
The thread below is a good read.
