I have older systems out there that work fine, just for what ever reason would be great to upgrade from a C5 -> C7 (due to no longer supported) or C6 > C7 (for updated packages).
Sounds like the upgrade tool is not quite an option... I was thinking...
What would be wrong with any "easy" script that did the following:
- Removed all packages with the --justdb option.
- Import the RPM-GPG-KEY-CentOS-7
- install the centos-release-7.3.1611 ... rpm
- yum -y upgrade
- yum groupinstall "GNOME Desktop" (for example)
and reboot of course.
Does that have any chance or working and be valid?
the correct method is
backup all user files, databases, and settings.
clean install c7, configure required packages.
restore user files, databases, and settings.
or easier
install c7 on new server
move over all services, functionality, etc. one by one.
This is how I do it. I just don't trust updates. Plus there is all sorts of detritus that builds up that you really don't want to drag along....
