Abstract:
A transition tool estimates a cutover time in a copy-free transition of storage objects. The transition tool determines how many storage objects of each type of storage object there are to transition from a source storage system to a destination storage system. The transition tool can measure an operation time for both the source storage system and the destination storage system. The transition tool can estimate an export duration using the source storage system operation time, the number of each type of storage object, and a number of operations for that type of storage object. The transition tool can estimate an import duration using the destination storage system operation time, the number of each type of storage object, and a number of operations for that type of storage object. A total cutover time can then be calculated from the export and import durations.
