Exemplary methods, apparatuses, and systems determine that a cache is to be migrated from a first storage device to a second storage device. The cache includes cache entries organized in a first list of cache entries and a second list of cache entries. Only a portion of all cache entries from the first and second lists is selected for migration to the second storage device. The selected cache entries and metadata for cache entries from the first or second list that were not selected are migrated from the first storage device to the second storage device.

Cache migration

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.
