-//   * All cache Upgrades are performed on backend start, must be finished

-//   * If the Upgrade is not implemented for transition from
-//     |kSimpleVersion - 1| then the whole cache directory will be cleared.
-//   * Dropping cache data on disk or some of its parts can be a valid way to
-//     Upgrade.
