UN-mounting orchids?

[JonnyBravo]

OK, here's one for you: does anyone have any tips for REMOVING orchids from their mounts? I can think of very few reasons for doing this, but once in a great while it must be done, and I'm wondering if anyone has any tricks they've used for making it a successful/ less traumatizing experience for the plant. I had a B Little Stars mounted on a big log, but the log was an inferior wood and rotted, necessitating its removal. Luckily, she had massive roots and due to the state of decay it was pretty easy to remove the orchid with minimal root damage. But I have a seedling Tolumnia which I purchased mounted on a machine-cut tiny "board", and would eventually like to put it on a more natural piece of wood. By then it will probably be pretty bonded its mount, and I worry about transferring it. Suggestions? Things that have worked in the past?
