1.0 doesn't have an "upgrade clause" so as far as I know you wouldn't
be able to
use the 1.0 work under the 2.5 license. So there's a compatibility problem.

You couldn't create such a derivative, so it couldn't be 2.5.
2.0 does have an upgrade clause, so you could mix 2.0 and 2.5 work and release
the results 2.5 .
