The intended audience for this IBM Redbooks publication are customers that have achieved partial implementation of the IBM DFSMS product suite and are looking to further their implementation through the use of the DFSMShsm product. It should be reassuring to know that many other customers have converted from products such as FDR/ABR, CA-ASM2 or CA-Disk to DFSMShsm. It is also important to acknowledge that such conversions are not completed overnight, and that the customer’s personnel will need to be intensively involved in their conversion project from its conception.
Most conversions require a period of product coexistence to allow the migration to proceed. This provides time for the aging of the prior product’s archive/backup data and reduces the data migration requirements. In some circumstances, it may be possible to hasten the conversion by installing enough disk to allow pre-restoration of data to subsequently backup/migrate with DFSMShsm.
This book book will take you through everything we have learned about performing these conversions. We cover the elements of preparation, activation, conversion, and exploitation, using examples to illustrate these activities from projects that we have performed.
