Abstract
This IBM® Redpaper™ publication describes how class transitions differ from the classic migration processes and how they can influence application performance levels.
Performance is focused on the following goals:
- Reduce the number of I/Os required to manage the storage
- Optimize data locations to the appropriate device type during its lifecycle
This paper applies to the IBM z/OS® V2.2 level.
