+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.

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. -- Mit freundlichen Gruessen / Best regards Oliver Dzombic IP-Interactive mailto:i...@ip-interactive.de Anschrift: IP Interactive UG ( haftungsbeschraenkt ) Zum Sonnenberg 1-3 63571 Gelnhausen HRB 93402 beim Amtsgericht Hanau Geschäftsführung: Oliver Dzombic Steuer Nr.: 35 236 3622 1 UST ID: DE274086107 Am 15.07.2017 um 08:25 schrieb Makrand: > Hi Gaith, > > CentOS 7 is significantly different than 6. e.g. 7 uses systemD.
