In the mainframe industry, there are many data migration products and many ways to migrate data. Some are controller based or appliance based, while others are host based. This paper focuses on host-based migration products, as they provide the most flexibility and the fewest operational restrictions. In most cases, it is helpful to use combinations of products or tools to accomplish a migration, because no one tool can do everything exactly the way the user may desire.
For example, the user may want to migrate from older to newer technology while, at the same time, moving to larger-capacity devices such as from an 3390-3 device to a 3390-9 system. One option in this scenario would be to have IBM’s System Managed Storage (SMS) do the migration with redirection, but this would not move files that have not been deleted and reallocated in a timely manner.
