Repotting can stress succulents, especially during hot weather. When a full repot is not ideal, cache potting can be a simpler way to stabilize the plant and improve presentation without disturbing the roots too much.
The key is to avoid trapping excess water. Make sure the inner pot drains well, check that the outer container does not hold standing water, and keep airflow around the plant.
When the season is safer and the plant is active, you can do a more complete repot with a suitable medium and pot size.
