server migration

Practical guide to weaving AI into a deterministic Linux server‑migration pipeline—keeping Bash, SSH, rsync, and Ansible—covering tool setup (apt/dnf/zypper), agentless inventory, using an OpenAI‑compatible model to draft plans and surface incompatibilities, rsync/restic dry‑runs, idempotent Ansible execution, validation and DNS cutover, plus a real‑world Ubuntu→Ubuntu/PostgreSQL upgrade and best‑practice guardrails.
