The only recommended way from 6 to 7 is to back up the data and do a fresh install. There were, I think, various upgrade tools, but they didn't work properly.

The only supported way from A to B is to back up the data and do a fresh install.
Red Hat had tools that did work only on genuine RHEL, and not even on all installed systems.


To install el7 now is a bit late -- it will be dead in one year. Both el8 and el9 do exists.
If you want spiritual equivalent/successor of CentOS [67], then look at {AlmaLinux,Rocky Linux}[89]
