OS Migration & Upgrades

Whether you're stuck on end-of-life CentOS 7, or simply need to move an existing Ubuntu or Debian environment up to a current LTS release, we handle the migration or upgrade cleanly — workloads, configuration, and data intact, with minimal downtime.

What's included

  • Compatibility audit of installed applications and dependencies
  • Clean OS migration (e.g. CentOS 7 → AlmaLinux) or in-place version upgrade
  • Application, service, and configuration state transfer
  • Library and dependency compatibility checks before cutover
  • Security hardening baseline applied post-migration
  • Rollback plan in place before any changes are made

Covers

CentOS 7 → AlmaLinux 8/9/10, Ubuntu LTS upgrades, Debian version upgrades, and general Linux distro migrations.

Why it matters

CentOS 7 stopped receiving security updates, which means every day it stays in production is a day of accumulating, unpatched exposure. But this isn't only a CentOS problem — if you're already on Ubuntu or Debian and just behind on versions, we handle straightforward upgrades too, not just cross-distro migrations.
