Repotting When Not In Active Growth?

I realize that the best time to repot anything is when it is in active growth. I have a brassidium that is potted dead center in what seems to be horrible medium that I'm very concerned about.

What are the consequences of repotting when not in active growth?

When a plant is not in active growth it will take longer to adjust to the new pot. Consequences may very. It could lose leaves or slow the start of new growths or blooms. But depending how bad the medium is, leaving it as is could be even worse, especially if it's causing the roots to rot. What is it that makes you describe the medium as horrible? Can you post a picture?

The medium has hardened and seems to be breaking down. It takes a long time for water to soak into it and drain out, which leads me to believe there is not enough oxygen left in it to keep the roots properly aerated. Certainly, I will post a pic once I get home from work.

I appreciate the help -- hopefully you guys can help me decide if it's worth it or not to repot!

It is all about roots.

The main reason why it is desirable to repot an orchid early in its growth cycle is that it is sprouting new roots that will take hold of the medium and sustain the plant's water needs (and fertilizer intake through the roots).

Repotting poses the risk of damaging the existing roots. If significant root damage is sustained and new roots are several months away from sprouting then the plant will be in danger of getting dehydrated.

If there is a legitimate need to repot "out of season", then do be careful to minimize root damage. The existing roots are the plant's only roots until the next growth cycle.
