When SQLines is the better choice
- Your project has a lot of PL/SQL or T-SQL to convert. Code conversion is the hard part of most migrations, and dbSlice does not do it.
- Your source is IBM DB2, Informix or Sybase.
- Your team prefers command-line tools driven by configuration files.
When dbSlice fits better
- The schema and code are handled (by SQLines, ora2pg or by hand) and you need the data moved and kept in sync until cutover, with a GUI the whole team can use.
- You need Firebird, SQLite or InterSystems Caché/IRIS.
- You need masked copies of production for test environments.
- You also send rows to Kafka, RabbitMQ or REST APIs.
- Running in production for more than six years in mission-critical environments, across multiple data centers and on-premises, with SQL Server, PostgreSQL, Aurora and InterSystems Caché/IRIS.
Using both
A common split: convert the schema and code with SQLines, review it, create the target objects, then use dbSlice to load the data, compare counts key by key, and run a nightly sync until the switch.
