Overview

Spanner migration tool is a stand-alone open source tool for Cloud Spanner evaluation andmigration, using data from an existing PostgreSQL, MySQL, SQL Server, Oracle or DynamoDB database.The tool ingests schema and data from either a pg_dump/mysqldump file or directlyfrom the source database, and supports both schema and data migration. For schemamigration, Spanner migration tool automatically builds a Spanner schema from the schemaof the source database. This schema can be customized using the Spanner migration tool schema assistant anda new Spanner database is created using the Spanner schema built.
