repotting advice for coelogyne rochussenii

[catasetum-ian]

hi,
i got a pot of coelogyne that is basically overgrown the pot that it is it, just need some advice here on what is the best way to repot it? got this plant after i saw an internet pic of the bloom where two pots were hang high up and as the bloom they form a "white curtain" like structure.

so what should i do from here?
1. dig the whole plant out and repot ( this would cause certain degree of root damage as they are tightly adhered to the pot)
2. dig the whole plant out, divide into two or three individual plants?
3. let let the entire pot sit in a bigger pot
..........sigh...what to do.................
