Converting Linux distributions to other distros
summary
Converts CentOS-family installs by swapping repos and reinstalling packages; usable tools include elevate, alma-deploy, migrate2rocky and a larger product that converts systems to RHEL, and the conversion method mostly works but needs extensive testing. Common failures are package dependency mismatches, kernel/arch differences, and CentOS Stream downgrades break because maintainers don’t test rollbacks. Boot issues include UEFI boot entries use hex and require PARTUUID fixes via blkid to get PARTUUID; cloud BYOS vs PAYG billing and secure-boot require manual handling.
