摘要： Method and system for migrating a virtual storage system from a source storage system having access to a source storage device to a destination storage system having access to a destination storage device is provided. A processor executable management application estimates a likelihood of success for a migration operation before the migration operation enters a cut-over duration during which client access to the source storage system and the destination storage system is restricted. The migration operation enters the cut-over duration if there is high likelihood of success for completing the migration during the cut-over duration or aborted, if there is a low likelihood of success for completing the migration during the cut-over duration.

摘要翻译： 提供了用于将虚拟存储系统从具有对源存储设备的访问的源存储系统迁移到具有访问目的地存储设备的目的地存储系统的方法和系统。 处理器可执行管理应用程序估计迁移操作成功的可能性，在迁移操作进入切换持续时间期间，客户端对源存储系统和目的地存储系统的访问受到限制。 如果在切割期间完成迁移的可能性很小，则在切割期间完成迁移的可能性很高，或者中止了迁移操作，则迁移操作将进入截止期。
