How to migrate from Ubuntu 18 to Ubuntu 19?
To migrate from Ubuntu 18 to Ubuntu 19: (1) review the official Ubuntu 19 migration guide for breaking changes, (2) update dependencies and configuration accordingly, (3) test thoroughly in a staging environment, (4) deploy with a rollback plan. Starting early gives you time to resolve compatibility issues before your current version reaches end of life.
Is it safe to run Ubuntu 18 in production?
No. Ubuntu 18 has reached end of life and security vulnerabilities are no longer patched. Critically, 5 CVEs affecting Ubuntu 18.x are in the CISA KEV catalog — meaning they are actively exploited in the wild. Upgrade to a supported version immediately.
