Running an end-of-life Ubuntu release or an old PHP version you're afraid to touch? I'll upgrade or migrate one Linux server to a supported stack, with a tested rollback path, so the change is predictable instead of a gamble.

Who it's for Teams and site owners with a production or staging server on an unsupported OS or runtime (for example Ubuntu 14.04/16.04/18.04, or PHP 5.x/7.x) who need it on a supported release without surprises.

Assessment: I review the server (read-only access or sanitized config is fine): OS, packages, services, PHP extensions, cron jobs, web server config, and dependencies that could break.

Plan: you get a written upgrade plan with risks ranked, a backup/snapshot step, and an explicit rollback procedure before anything changes.

Upgrade or migrate: in-place upgrade or move to a fresh server, whichever is safer for your setup, scripted with Ansible or Bash where it helps repeatability.

Verify and hand off: I test the site/app and services, fix compatibility issues, and leave you a runbook.
