Afaik, you will still have to migrate, its either NOW or NEST (Omnesys supported) platforms including Pi/Kite.
Have they migrated ur a/c? secondly, you can just use the latest NEST 3.14 from download section and should work out-of-the-box.
If you have more complex setup like RTD/Excel charts/Link with AmiB/NT etc then you need to research more but for simple tasks within NEST it should work fine.
