An electronics company operates its website on B2C Commerce. The company recently decided to update its Customer Service portal from a homegrown solution to Service Cloud in order to take advantage of Assisted Order Placement through the 'Order on Behalf of feature in the Service Cloud console.
The company currently has 3 million customer records in its B2C Commerce database that need to be migrated into Service Cloud.
How should a Solution Architect manage the export from B2C Commerce-and import the initial batch of customer records into Service Cloud in an efficient manner?
