What free automation tools exist for Data Migrations between Old and New Systems?

What approaches should I use to ensure data was migrated correctly ?

I'm a beginner Tester in web applications, E-Learning System.

  • Define "best". Cheapest? Best for integration ? Runs on Windows ? please post some requirements. Like which systems / databases. There is no generic solution, just specific ones depending on platforms. – Michael Durrant Jun 3 '17 at 10:24
  • Also consider asking for 'good' instead of 'best'. We're moving towards 'good practices' over 'best practices' in the industry and I believe this applies to tools too. – Michael Durrant Jun 3 '17 at 10:26
