BDeclarative schema supports RENAME TABLE', so the data will be migrated to the new table automatically.

CDefine the table and columns mapping in the db.schema_whitelist.json

Show Suggested Answer

Suggested Answer: C

When renaming a table in Magento, to prevent data loss, the developer must define the table and its columns mapping in the db_schema_whitelist.json file. This declarative schema approach ensures that the data migration tool knows about the changes and can migrate data from the old table to the newly named table without losing any data.
