Very beautiful! You must be happy to have it!
A 25g pot is quite heavy and difficult to manage when the planting time comes,which will inevitably result in many broken roots,something certainly survivable but not the best for the plant and its stability. If you have one more month of warm temperatures(20C high),it would probably be better to ground plant it now instead of repotting it. The drainage in the ground is usually better and the plant will be more stable,even with its current root system. And with 20C temperatures,it will have the chance to grow some more roots and be better prepared for winter! A frost and low temperatures in general,are harsher to potted plants than ground planted ones and rot is less likely in the ground if you have an airy mixture and plant it mounded.
Otherwise,it may be better to leave it as it is till spring,and move it under an overhang in cold nights. The more sun it receives at this time of year,the less the chance of rot
