We know that many of you have developed nice basic templates for MIR. We have put quite some effort into the possibility of an easy transition from Vienna MIR to MIR Pro for our users. But you have to be aware of the fact that under the hood they are _completely_ different programs. Our developers have some ideas how to make "old" MIR Projects work with the new engine, but I can't promise you that you won't have to rebuild existing setups.
Thanks for your understanding!
