An import for updating personas must include Account Number. When we map the fields in an import, we must select a key field to search for potential duplicates. If we want to import information for multiple Personas, we must use both the Account Number and the Persona Type as the key.That way, Account Number key will force the import process to search for the account and the key of persona will select the correct persona to be updated.

Please note, that we cannot update any salutations using this import and we cannot create new Personas, we can only update existing Personas.
