I think it will be better to redeploy the compute nodes from scratch.
Juno is supported on el7 only.
From my experience with upgrading from 6 to 7, it's a lot of
hassle,
because the upgrade process only takes care of base the programs.
After the upgrade you will have to upgrade/downgrade/remove manually
the packages that where not updated.
Best regards,

Hello
We have an relatively big OpenStack setup (> 150 Compute Nodes) based on
CentOS 6.5 with the RDO Icehouse release.
We now considering an upgrade to Juno, is there a best practice out there
how to do it and how is it with the depending CentOS upgrade to 6.6 or even
7.0?
Any help is appreciated!
Thanks,
Chris
