D.

Migration will restrict all activities on the source system

Answers
D.

Migration will restrict all activities on the source system

Suggested answer: B

Explanation:

When a source system is in restricted mode, certain maintenance tasks, like file system cleaning, are unavailable. This restriction is typically applied during migrations to prevent data inconsistencies, ensuring a smooth transfer of data to the new system.

During the migration process from an older Data Domain system with cloud tier capabilities to a new PowerProtect DD appliance, the source system operates in a 'restricted mode.' This restricted mode limits specific functionalities, including file system cleaning. File system cleaning is a maintenance operation that reclaims storage by deduplication and cleaning up obsolete data. However, to prevent data inconsistency or interference during migration, this functionality is temporarily disabled on the source system, thus ensuring data integrity until the migration process is completed.

The restricted mode ensures that all critical operations remain stable and predictable on the source system, which is essential for a smooth migration to the new environment.
