The term 'migration policy' in storage systems refers to:

Explanation:
Migration policy in storage systems defines how data moves between storage tiers based on how it’s used. The idea is automated tiering: frequently accessed data stays on fast, expensive storage, while infrequently accessed data is moved to slower, cheaper tiers. This helps balance performance and cost and is a key part of lifecycle management. The policy relies on access patterns and related thresholds (like last access time or access frequency) to decide when and where to migrate data. It’s not about routing network traffic, user authentication, or backing up data, which serve different purposes in a storage environment.
