I'm lookin for suggestions on the "best" method to migrate specific Business Unit data from an existing Dynamics CRM online instance to a new online instance that has been stood up for them. This could be as basic as moving accounts and associated contacts, through to including the leads, quotes, history, opportunities etc.
The new business unit does not want to keep the existing business structure or any of the modifications that are in place in the existing instance as they prefer to start clean and make thier own adjustments to match thier business.
Any suggestions would be appreciated.
