Hi Jai
Yes, this should work. For example, if you have a spreadsheets of accounts from various sources and you use the data migration tool to load them into C4C, they will replicate to CRM (assuming the communication arrangements and everything is configured). Now, please consider that C4C has validation rules and SAP CRM OP has more - so there could be data errors when integrating if it doesn't meet the restrictions (like tax jurisdiction codes, or something like that).
