CentOS 6 to CentOS 7 Upgrades

CentOS 6 to CentOS 7 Upgrades

We're looking to upgrade our production nodes from CentOS 6.5 to CentOS 7.5. I don't think there is any way to "upgrade" to 7.x from 6.x and this would most likely require a fresh OS install for each node. Are there any best practices/warnings/advice for going about this, and is there any way to do this without having services go down? 

 

Thanks in advance.
