CRM Migrate is a tool to allow you to easily migrate from SalesForce to Microsoft Dynamics CRM. It does all the things that you'd expect it to
- Grabs the data from salesforce (using CSV files or the API)
- Maps standard objeccts automatically
- Allows you to map custom objects and custom fields
- Transferrs the data into any style of CRM - hosted, live or on-premise
The beauty of it, and the reason that it beats the DMM (data migration manager) is that it is iterative - you get a problem, you fix it you continue.
I work closely with QGate on this project who are the distributors of this product and are great to work with.
We've also got a version for migrating from Goldmine to MS Dynamics CRM
