@openmindz, Thanks for the sharing.
@cjcox and I were talking about in-place major version upgrade/conversion like from Centos 7 to either Rocky/Oracle/Alma Linux 8. Elevate was a fork of RH’s leapp(for RHEL only) that fill the missed leapp datasets for centos. Yes, I tried and like migrate2rocky script and Oracle and Alma Linux also have similar scripts also.
