+1 for Oliver’s suggestion – you would run into a lot of issues trying to upgrade from 6.5 to 7, you are much better off simply building a new CentOS7 management server and pointing this at your existing database before decommissioning your old 6.5 server.
Just keep in mind to *not* use the “deploy-as” option with cloudstack-setup-databases – simply use the instructions for “additional management servers” in http://docs.cloudstack.apache.org/projects/cloudstack-installation/en/4.9/management-server/index.html#additional-management-servers . It’s also a good idea to back up your databases beforehand.

Hi,
upgrades where runlevel management significantly changes is always
connected with a lot that can go wrong.
Its not as worst as upgrading an older ubuntu to ubuntu 16, but you
might end up being forced to replace the node.
Its suggestable that you simply create fresh centos 7 and migrate the
services.
But in the very end, centos 6 has still some years left of update
maintenance. So as long as you dont run into any compatibility issues,
where you need centos 7 with its newer versions, you should stay with
your centos 6.

Hi Gaith,
CentOS 7 is significantly different than 6. e.g. 7 uses systemD. There are
a lot of other changes as well. Speaking purely from OS upgrade POV, I
think you will run into lots of issues after the upgrade.
From ACS POV, I don't see any major difference or advantage. (although I am
not very about this)
