Execute database migrations across ORMs and platforms with zero-downtime strategies, data transformation, and rollback procedures. Use when migrating databases, changing schemas, performing data transformations, or implementing zero-downtime deployment strategies.
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
# Database Migration
Master database schema and data migrations across ORMs (Sequelize, TypeORM, Prisma), including rollback strategies and zero-downtime deployments.

- Performing schema transformations
- Moving data between databases
- Implementing rollback procedures
- Zero-downtime deployments
- Database version upgrades
- Data model refactoring
## ORM Migrations
### Sequelize Migrations
```javascript
// migrations/20231201-create-users.js
module.exports = {
up: async (queryInterface, Sequelize) => {
await queryInterface.createTable("users", {
id: {
type: Sequelize.INTEGER,
primaryKey: true,
autoIncrement: true,
},
email: {
type: Sequelize.STRING,
unique: true,
allowNull: false,
},
createdAt: Sequelize.DATE,
updatedAt: Sequelize.DATE,
});
},
down: async (queryInterface, Sequelize) => {
await queryInterface.dropTable("users");
},
};
// Run: npx sequelize-cli db:migrate
// Rollback: npx sequelize-cli db:migrate:undo
```
### TypeORM Migrations
```typescript
// migrations/1701234567-CreateUsers.ts

How to install
mdr add wshobson/agents/database-migration@sha256:d388db68c9f86bebThe line at the top of this page pins the label git:20260522.be57c0b, 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.
