You’ve got a problem. The number of files you have is growing steadily, but your naming conventions are outmoded and have to be adapted. Or you want to integrate other data centers into your system and their naming conventions don’t match.

But changing dataset names is a lot of work: You have to rename the file in the catalog, modify the DD statements in the JCL, resolve symbolic parms, adapt IMS DYNALLOCs and utilities – and on and on.

The upshot: Manual migration of file names is time-consuming, error-prone and, as a result, expensive. That’s why there’s DSN/Change. If you want to carry out migration automatically, reliably, and at low cost, DSN/Change is the right tool for your data center.

Rules for conversion are specified in the ISPF dialog. Extensive log and rollback procedures guarantee 100% reliability. A DD statement reformatting feature and a DSN cross-reference round off this indispensable tool.
