overgrown epidendrum

[Shiffdaddy]

I recently received an epidendrum radicans (orange) that is in a huge pot and must weigh over 100 lbs. It is severely root bound and definitely needs to be divided. Will the plant kill itself if not repotted or will it just continue to grow and bloom. It's supposedly been fine the last 8 years but it seems like the plant would strangle itself. Thanks for any responses
