Cutting Back A Money Tree?

[agardener]

I have a very old and large money tree (crassula ovata) that lives most of the year in our conservatory. I know it to be at least 50 years old, it is about 3 feet high and about 2 feet wide. The trunk is several inches in diameter. It's very healthy with only an occasional mealy bug and is very bushy.
Its size is the problem, I obviously don't want to lose it but its getting too big for its corner of the conservatory. I have trimmed bits off it at times but it now suggests a more radical pruning. The question is how much and when? And should I combine it with repotting?
Opinions please.

I'd root some cuttings of it before you do anything. I would either repot first, let it settle, them prune or prune first, let it settle them repot but not together.

Thanks for your advice woofgang, I'm pleased to say I do already have a cutting from it, over the years I've always kept a couple just in case. I'm leaning towards repotting first to give it some food to recover with before I prune.
