I have to migrate the data and related attachments associated with the data from SFDC to Microsoft Dynamics 365. What are my options? There are close to 100,000 cases and about 2 to 3 attachments associated with each case. What is the best way to download these attachments to be moved over to Microsoft Dynamics 365 CRM tool. 

Hi I need to know if the below scenario is possible as everything i have read so far says no.

I have a case with a email linked to it. The email also has attachments that are linked to it. What I would like to do is export all the related information out of Salesforce.

Is this possible?
