Database migration best practices for schema changes, data migrations, rollbacks, and zero-downtime deployments across PostgreSQL, MySQL, and common ORMs (Prisma, Drizzle, Kysely, Django, TypeORM, golang-migrate).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# /supergraph:database-migrations Safe, reversible database schema changes for production systems. Announce: "🗄️ /supergraph:database-migrations — checking blast radius and migration safety..." ## When to Activate - Creating or altering database tables - Adding/removing columns or indexes - Running data migrations (backfill, transform) - Planning zero-downtime schema changes - Setting up migration tooling for a new project ## Steps ### 1. Check blast radius (MANDATORY before writing any migration) Use `CBM_PROJECT`: `search_graph` schema/model symbols, `trace_path` inbound and data-flow, then validated `dependencies`, `hubs`, and `test-gaps` recipes. Schema changes to hub tables (e.g. `users`, `orders`) ripple through repositories, queries, services. If blast radius > 20 files → STOP and discuss with user. **Serena symbol-level impact (optional):** ``` mcp__serena__find_referencing_symbols(symbol=<column_or_model_name>) ``` Finds ORM field references that graph tools see only at file level — e.g. a Prisma field rename that `query_graph` sees as "file touched" but Serena sees as "12 usages in service layer". Skip if Serena unavailable. ### 2. Choose migration pattern …

How to install
mdr add datit309/supergraph/database-migrations@sha256:7cec34723c6d01b4The line at the top of this page pins the label git:20260710.92fdf2f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
