I would suppose that it does depend on the size of the tree you want to move, but in any case this would be attempted around December so that it would have a chance to re-establish itself. This tree can grow from ludicrously large cuttings so one could consder the transplanted tree as one, with the bonus of some existing roots.
Either way a well watered cutting can grow amazingly fast, 3m+ a year is not out of the ordinary in it's second year so a replacement is an option.
