CentOS 7 and 8 migration
CentOS 7 stopped receiving security updates on 30 June 2024. Every CentOS server still running today is exposed to every kernel and OpenSSL vulnerability found since. That includes a lot of web servers, cPanel hosts, monitoring boxes and application servers people forgot about.
We inventory, convert in place where the application allows and rebuild where it does not. cPanel, Plesk, and PBX systems need their own paths and we know them.

How we work
Linux fleets stay healthy through automation and discipline. We build servers from a standard image with Ansible, patch them on a schedule with a staging ring, keep SELinux or AppArmor on, and log everything to a central collector. The result is a fleet that looks the same everywhere and can be rebuilt from Git.
Migrations, whether CentOS to Rocky, RHEL 8 to 9 or Windows to Linux, are done per workload with a test pass, a cutover window and a rollback. We coordinate with application vendors and keep the paperwork for compliance.
Subscriptions and licences are reviewed as part of the work. Plenty of businesses pay for RHEL where Rocky would do, or run unsupported CentOS where a subscription would satisfy an auditor. We fix both directions.

Frequently asked questions
Can I still get CentOS 7 patches?
Only through paid extended lifecycle offerings (TuxCare, CIQ). Use them as a bridge, not a destination.
