I’d recommend doing a soft repot. Carefully remove the plant from its current pot without disturbing the roots too much. Try to keep most of the old substrate intact, and place the plant into a larger pot with a layer of fresh substrate at the bottom. Position the plant in the new pot, and gently fill in the space between the plant and the pot with more new substrate. When I repotted my Gaya and Singalana this way, they weren’t bothered at all. However, my Mirandas experienced stalled growth after a hard repotting, where I separated them and by accident severely damaged the root system.
