I looked into this a few years ago (before M8000 & M7000 came out) because the Zee derailleurs were really cheap. The posts I found on MTBR about it - including one from OneUp which is one of the companies like Wolf Tooth that started out making big-cog kits - is that it might work on a hard tail but the chain length needs to be exactly right. It just has barely enough wrap. On a full suspension it's probably not going to work.

You have an M6000, right? What are you trying to do? If it's broken, any of the 11 speed RD's will swap for that
