Yes that's correct, earliest version you could directly upgrade from is
3.12. That's what i had to do and it all went well.

Well i wouldn't recommend in the long term. After the upgrade it is advised
to bump the op-version[1] and that could be a problem with the old clients.
But as i don't know the supported feature-sets i leave that question to the
experts here ;-)
