The reasons behind it are mostly about not enough time to properly
maintain parallel releases for EL6 and EL7. We've experienced that
need to support two branches requires a lot of energy that is better
spent to make EL7 release more mature.

Upstream still supports Juno for Python 2.6, but support will be
dropped in Kilo (the next cycle).

As for the upgrade path, yes, you'll need EL7 to be able to use RDO
Juno. You will need to migrate to EL7 in the future anyway if you're
planning to use pieces from Kilo.

BTW the same approach is true for the next version of Red Hat
commercial OpenStack distribution (RHEL-OSP6 based on Juno).

I hope that helps,
