Course Overview: What You’ll Learn in AI Database Migrations: Safe Schema Changes in Production
AI Database Migrations: Safe Schema Changes in Production
A hands-on, AI-first course. 8 lessons, lifetime access, new frameworks you can use tomorrow.
What You Will Learn
By the end of this course, you’ll walk away with real, shippable outputs — not theory. Here’s what you can expect:
- A mental model for reversible vs. irreversible migrations
- The expand/contract pattern (6 steps) for zero-downtime schema changes
- Writing safe, idempotent migration SQL for Postgres and MySQL
- Using AI tools (Cursor, Claude, Copilot) to author and review migration scripts
- Testing strategies: shadow DBs, migration dry-runs, and load-tested promotions
- Rolling back safely — and knowing when rollback is NOT the right move
- ORM-specific gotchas (Prisma, Django, Rails, ActiveRecord, Alembic, Drizzle)
Full Course Breakdown
Every paid lesson in the course, at a glance. Lesson 1 (this page) is free — Lessons 2–8 unlock with purchase.
The Mental Model: Reversible vs. Irreversible Schema Changes
Every migration falls into one of five categories. Only two are safe to ship on a Friday afternoon.
The Expand/Contract Pattern in Six Steps
The only reliable pattern for zero-downtime schema changes. Once you internalize it, every other pattern is a variation.
Writing Safe Postgres Migration SQL
The rules that stop migrations from locking your production table for 20 minutes.
AI-Assisted Migration Authoring and Review
Let AI draft the boring parts. Keep human judgment for the rollback plan.
Testing: Shadow DBs, Dry-Runs, and Load-Tested Promotions
If your first production run of a migration is the real one, you are playing roulette.
Rollback Strategy — And When NOT to Roll Back
The migration is live. Something is wrong. Now the harder question: forward or back?
ORM Gotchas: Prisma, Django, Rails, Alembic, Drizzle
Every ORM has a different story for what "safe migration" means. Know yours.
Who This Course Is For
- Backend engineers who keep hitting locks during schema changes
- Solo founders running production Postgres who need a playbook, not folklore
- SREs building migration automation and CI gates
- Tech leads writing a migration review checklist for the team
What Makes This Course Different
Hands-on from lesson two. You build alongside the videos — no passive watching. Every lesson ends with an exercise you can run with your own AI stack.
Evergreen, not hype. The underlying frameworks outlast any specific tool. We name specific AI products so examples feel concrete, but the decisions stay valid if you switch tomorrow.
Opinionated. There’s a clear sequence, clear recommendations, and clear things to avoid. You won’t leave the course wondering which of six approaches to take.
