Moving plant between mounts?

[Trollsvans]

I've recently aquired a Schoenorchis seidenfadenii, which is mounted on a terracotta giraffe (wtf of the day, indeed).
I'd like to transfer it to my drip wall tank.
How do I best proceed to dismount it?
It's somewhat established, with a few roots attached to the terracotta, but most are loose.
It's also in spike, I might add, with blooms opening any month now.

I'll try to get a pic this weekend.
