If you haven’t tried the Talend Framework yet, see what others are saying.

“We have used the Talend Framework on a number of occasions most recently on a project to migrate around 1 million records into Salesforce from external sources. We would never have made the project deadline without the Talend Framework. This gave us the head start we needed on the migration. I would recommend using the Talend Framework if you are thinking of embarking on a Data Migration project any time soon.”
