CockroachDB Migrations
MOLT Migration Toolkit
The MOLT (Migrate Off Legacy Technology) toolkit enables simple, safe, minimal-downtime database migrations to CockroachDB. MOLT combines schema transformation, distributed data load, continuous replication, and row-level validation into a highly configurable workflow that adapts to diverse production environments.
Migrations with MOLT are resilient, restartable, and scalable to large data sets.
Cockroach Labs MOLT tooling helps you at each step of a migration to de-risk your migration. The three tools in the toolkit are purpose-built to ensure your migration is simple, and that your data is kept safe and secure through the migration process.
MOLT Convert
The MOLT Convert converts a source database schema to a CockroachDB-compatible schema.
Supports schema conversion from PostgreSQL, MySQL, Oracle, and SQL Server.
MOLT Fetch
MOLT Fetch performs the core data migration to CockroachDB via cloud storage, local file servers, or direct copy.
Supports PostgreSQL, MySQL, and Oracle dialects.
MOLT Verify
MOLT Verify checks for data and schema discrepancies between the source database and CockroachDB.
Supports PostgreSQL, MySQL, and Oracle.
