The workflow moves tables into PlanetScale Vitess while the source database continues serving traffic.

PlanetScale says developers can bring an existing MySQL database into PlanetScale Vitess through the pscale CLI without stopping the source database. The process connects the database to a production branch as an external keyspace, then uses a Vitess MoveTables workflow to move its tables. During copying and replication, the source keeps handling traffic; operators can change reads first and writes afterward when ready. The example commands create an external keyspace called mydb_source and launch import_mydb for all tables, with secondary keys deferred. Operators can check progress with the MoveTables status command or the dashboard’s Workflows page. PlanetScale’s changelog, dated September 29, 2026, says the import is now available.
