This is because as the version is updated, some interfaces and methods may change, causing the existing code to fail. However, if the migration process follows the principle of backward compatibility, the impact should be limited. To ensure that the migrated version can correctly handle the existing transaction tracking data, the development team needs to fully test and validate the new version's ability to process old data during the migration process. Meanwhile, the integrity and security of the data should  be ensured during the migration process to avoid data loss or tampering. In summary, although version migration may have a certain impact on transaction tracking data, it can be mitigated by following appropriate practices."}]}],"pr":"256becdd110702392e39e345df708c0d0f646b18f62d9ee5f2a08745586e2903"}
