Overview

Migrates a vault to the current storage format by reading it through its existing backend and rewriting it through the current-format writer, then atomically swapping the file into place. Each gem's created_at carries over as the source backend reports it -- which for a format-2 vault is a fresh stamp, its stored times being unreadable (see LegacyTarvault).
