What is the primary reason for using an Account template when migrating data?

Using an Account template when migrating data primarily ensures that all associated child objects are captured during the migration process. This is crucial because an Account in Salesforce can have related objects such as Contacts, Opportunities, and Cases. By applying a template specifically designed for Accounts, you can define the structure and relationships that need to be preserved throughout the migration.

The use of these templates helps maintain the integrity and interconnectedness of the data. For instance, if only the primary Account information were migrated without considering the associated child records, it could result in orphaned records or loss of critical relationships, leading to incomplete data representation.

While other options may have some relevance in different contexts, they do not specifically address the core purpose of employing an Account template, which centers around comprehensive data migration that includes relationships with child objects.
