I agree with the post that advises against repotting, however the plant is clearly in need of change, so I would move it into bark, LECA and charcoal mix, or something along these lines. I have been growing cattleyas for over a decade, and none liked medium with spagnum moss in it.

Sphagnum is a valid choice, often the best, for a weak nearly rootless plant while it recovers. Once it begins something closer to normal healthy growth then it does need to move to a more appropriate mix for long term Catt health.
