I have to migrate data from CRM 4.0 to MS CRM Online & customer has around 35GB data now my question is which would be the best way to migrate the data?
A: Using CRM 4.0 Data Migration Manager to export the data & then using import the data using ConfigurationMigration? Is that be viable solution? B: Export the data from CRM 4.0 using Data Migration Manager & then upload it using SSIS or custom code?
Any idea how much time usual it should take to upload that much data (35GB this includes Account, Appointments, Lead & few custom entities)
