[Rdo-list] [Openstack] Upgrade from Icehouse to Juno on Centos 6.5

[Michael Dorman]

Hi Chris,

We haven’t yet gone to Juno, but in preparation for that we’ve been upgrading to CentOS 7.  I have been using the CentOS Upgrade Tool, the process described here: http://wiki.centos.org/TipsAndTricks/CentOSUpgradeTool

It’s time consuming and causes 45-60min of downtime per server.   But once it’s done it’s thing, it seems to be working well.

Mike

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
