Abstract
Exemplary methods, apparatuses, and systems determine that a cache is to be migrated from a first storage device to a second storage device. Each cache entry within the cache includes a first indicator to indicate whether or not the cache entry has long-term utility. Only a portion of all cache entries are selected to be migrated and the portion is selected from cache entries with the first indicator set to indicate long-term utility. The selected cache entries and metadata for cache entries that were not selected are migrated from the first storage device to the second storage device.
