Question 1 of 30

\"Globex Enterprises,\" a multinational corporation, is undergoing a major data migration project. Their legacy systems, developed over the past three decades, use a variety of outdated country codes, many of which are no longer valid according to the current ISO 3166-1 standard. The company is now implementing a new, centralized database system and wants to ensure that all historical data is accurately represented and accessible. The data migration team is debating the best approach for handling the formerly used country codes defined in ISO 3166-3 to ensure data integrity and minimize disruption to business operations. Considering the need for both backward compatibility and adherence to current standards, which of the following strategies would be the MOST comprehensive and effective for Globex Enterprises to adopt during this data migration?

Maintain a cross-reference table mapping the obsolete ISO 3166-3 codes to their current ISO 3166-1 equivalents, update the core database system to support ISO 3166-3, implement a data validation process to identify and correct inconsistencies, and provide comprehensive training to the data management team.
Continue using the existing country codes in the legacy systems and create a separate data warehouse for new data using the current ISO 3166-1 standard, effectively isolating the old data from the new data.
Update the core database system to use only the current ISO 3166-1 standard and discard any data associated with obsolete ISO 3166-3 codes to ensure consistency and avoid potential errors.
Provide extensive training to the data management team on the differences between ISO 3166-1 and ISO 3166-3 and rely on manual data conversion during the migration process without updating the database system or implementing data validation.
