How to Migrate from RHEL to RLC Pro Without Re-Architecting

I wrote this guide for CIQ covering how to convert a running RHEL system to RLC Pro, without rebuilding servers or re-certifying your application stack.

The core of the post is Enterprise Linux binary compatibility. Because Rocky Linux builds from the same source RPMs as RHEL, the kernel ABI stays stable, shared libraries match, and your applications, Ansible playbooks, and automation carry over without modification. What actually changes is repository URLs, package signatures, and OS branding. That’s it. The migrate2rlc script handles the conversion on a live system, and the post walks through the full process: environment assessment, collecting CIQ portal credentials, running the migration, and validating the result.

I also covered what you get on the other side. LTS version pinning, FIPS 140-3 validated packages on the .2/.6/.10 releases, commercial support tiers, and IP indemnification. The migration is the starting point, not the finish line.

Migration content sits at the intersection of technical depth and business case, which is the kind of writing I enjoy most and where my sysadmin background actually earns its keep.
