RHEL 7 to RHEL 8 migration assistant for production servers

The moment this problem surfaces is when an ops team gets told their CentOS 7 or RHEL 7 servers need to move to AlmaLinux 8 before EOL, and the engineer assigned to it opens a diff of what changed between major versions and realizes there is no safe, auditable path — just a wiki page, a lot of tribal knowledge, and the terrifying phrase 'test in staging first.' The complaint is explicit: 'the amount of work involved in changing to a new OS for Production servers is daunting.'

This gap exists because migration tooling is deeply unsexy work that distro vendors have no commercial incentive to build well. AlmaLinux's revenue model (support contracts, cloud images) doesn't reward them for making migration fast — a botched migration that leads to a support contract is arguably fine by them. Meanwhile, the actual pain falls on individual sysadmins whose frustration never aggregates into a product brief anywhere.

What exists today is generic documentation, community forum posts, and manual checklists. None of it knows anything about your specific server: what packages you have installed, what services are running, what custom repo configs will break, which scripts reference paths or syscalls that changed between RHEL 7 and 8. Users are doing this entirely by hand, which means every team redoes the same analysis from scratch.

This is a business because every company with aging CentOS 7 infrastructure faces this migration before the 2024 EOL cliff, and then faces it again every major version cycle. The cost of a botched production migration — downtime, rollback, incident postmortems — is concrete and large. A tool that turns a week of careful manual analysis into a two-hour audit with a tracked remediation list is worth real money to an ops team that does this even twice a year.

What to build

Build an agent that runs on an existing RHEL 7 / CentOS 7 server, inventories installed packages, running services, cron jobs, custom repo files, and shell scripts, then produces a prioritized compatibility report against AlmaLinux 8 — flagging removed packages, changed default paths, deprecated syscalls, and broken repo URLs — with a generated remediation script for each flagged item.

Where to start

Start with the single most common breakage: Python 2 vs Python 3 defaults and the packages that depend on them. This alone accounts for a disproportionate share of post-migration breakage complaints and is fully automatable to detect — win on that one thing before broadening.

The hard part

The compatibility analysis has to be accurate enough that engineers trust it with production servers — one false negative that causes a migration failure destroys credibility immediately, so the early version needs to be conservative and explicit about what it doesn't check rather than appearing comprehensive when it isn't.

How it makes money

One-time purchase per migration project (e.g., $199 for up to 10 servers, $599 for up to 100) with an optional annual subscription for teams running rolling migrations or who want to re-scan after remediation.
