How do I repot this Asctm. miniatum?

[Gage]

Any creative advice for removing the roots from the plastic basket so I can move it to a wooden basket? I certainly don't want to cause any unnecessary damage. I was thinking of waiting till I see roots growing, then soaking it in warm-ish water and gently removing each root one at a time. Then I guess I would use tin snips to cut the basket up where necessary. You guys got anything better?
