The order of uploading Salesforce objects during an FSC data migration is important to ensure data integrity and avoid errors. The recommended order is:
Accounts and contacts: These are the coreobjects that store the basic information about the customers and their relationships. They should be uploaded first to establish the foundationfor the FSC data model4.
Financial accounts: These are the custom objects that store the financial information about the customers, such as balances, interest rates, fees, and transactions. They should be uploaded after the accounts and contacts, and linked to them using lookupfields5.
Account groups and households: These are the custom objects that group the accountsand contacts based on common attributes or relationships, such as family members or business partners. They should be uploaded after the financial accounts, and linked to them using junction objects6.
