Use when dealing with cognee database migrations — understanding when they run automatically, checking or repairing migration state with cognee-cli upgrade/downgrade/stamp/current, a write blocked by a failed migration, authoring a new Alembic (relational schema) revision or a graph/vector data migration, or moving data between systems (relational DB import, memory export/import).
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 migrations cognee has **two migration chains**, run together: | Chain | Changes | Lives in | Revision stored in | |---|---|---|---| | **Relational schema** (Alembic) | Tables and columns of the relational DB (users, datasets, ACLs, pipeline runs, …) | `cognee/alembic/` (`alembic.ini` is in `cognee/`) | `alembic_version` table | | **Graph/vector data** | Cross-store data rewrites (re-keying node ids, adding graph columns) across graph DB, vector DB and relational ledger | `cognee/modules/migrations/` (`registry.py`, `versions/`) | Per dataset: `dataset_database.migration_revision` (access control on). Globally: `global_database_version.global_migration_revision` (access control off) | ## Use it ### They run by themselves `run_migrations()` applies the relational chain first, then the data chain. It runs: - at API server startup (and in the Docker `entrypoint.sh` before gunicorn); - on the first write in an SDK or CLI process (`remember`, `add`, `cognify`, `improve`, memory imports), once per process; - when you call `await cognee.run_migrations()`. A fresh database is built by running the whole chain (no stamping). At …

How to install
mdr add topoteretes/cognee/cognee-migrations@sha256:4639bceaa81eee4cThe line at the top of this page pins the label git:20261018.6286687, 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.
