Cutover Diary: The Leftovers When You Move an AI Workflow to Free Infrastructure

Описание и применение

Перенос AI‑бота на бесплатную инфраструктуру потребовал тщательного планирования: от фиксации старой конфигурации до параллельного тестирования в режиме тени. После устранения оставшихся проблем (логика повторных запросов, шаблон подсказки, расписание) миграция прошла успешно.

Задача

Migrating an AI review bot from a paid endpoint and VPS to free infrastructure introduced hidden issues such as leftover retry logic, prompt formatting, and scheduling mismatches.

Результат

The migration succeeded after addressing three key leftovers: reworked retry logic, prompt template, and cron schedule. Shadow mode revealed prompt formatting differences, and a week of overlap ensured stability before decommissioning the paid endpoint.

Рабочий процесс

• Freeze old configuration and snapshot prompt, retry policy, and server setup
• Run shadow mode to compare outputs of old and new pipelines
• Flip traffic for a single repository to test live performance
• Keep old server alive for seven days as rollback target
• Delete old endpoint after a full week of successful reviews

Доказательства

The plan had five steps, and the order matters because each one gives you a way back

Three things did not migrate cleanly, and each one is a lesson about free infrastructure
