There is an Ignite session with the following title:
Migrate Salesforce.com to Dynamics CRM Online Cloud using Dynamics Lifecycle Services
In this session we describe the mechanisms available to convert a Salesforce.com organization to Microsoft Dynamics CRM Online. The mechanism to move from Salesforce to CRM Online has been greatly simplified and streamlined to be orchestrated through the Microsoft Dynamics Lifecycle Services (LCS) portal that customers can use. We also describe the LCS process and what the customer needs to do in order to move to CRM Online.
