I understand not wanting to break a pot. That type of ceramic pot with dish attached can be upwards of $8 a piece. Losing the plant over the pot is something to weigh out. Often you can buy a ZZ plant at Lowe's for around $9 or less. So about the same price as the pot. But perhaps there is sentimental value to either the plant or the pot? Plus it grows very slowly, any damage to the plant would further slow down growth.
