Migrates databases between providers (Postgres, MySQL, Supabase, PlanetScale, MongoDB). Reads source schema, generates migration scripts, handles data type mapping, foreign keys, indexes, triggers, stored procedures. Validates migration with row counts and checksums. Generates migration-plan.md with step-by-step execution guide, rollback procedures, estimated downtime.
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 Migrator Move schemas, data, and logic between database providers. This is a cross-provider migration engine, not a schema designer: it handles data type incompatibilities, provider-specific SQL dialects, foreign key ordering, sequence and auto-increment translation, trigger rewrites, and stored procedure conversion. It validates with row counts and checksums and produces an auditable migration-plan.md. ## Contents - references/schema-discovery.md -- Extraction queries for relational, MongoDB, Supabase, and PlanetScale sources. - references/type-mapping.md -- Data type maps (PG/MySQL/Mongo) and SQL function translation. - references/script-generation.md -- DDL, sequence, trigger, procedure, and view translation. - references/data-migration.md -- Export, transform, and import commands per provider. - references/validation.md -- Row count, checksum, FK integrity, index, and spot-check queries. - references/rollback-and-downtime.md -- Rollback scripts, backup/restore, downtime estimation. - references/migration-plan-template.md -- Full migration-plan.md output template. …

How to install
mdr add onewave-ai/claude-skills/database-migrator@sha256:cb6ffddea8e9c0e3The line at the top of this page pins the label git:20260608.d82d20f, 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.
