    Abstract

    The z/OS® Distributed File Service zSeries® File System (zFS) is the strategic z/OS UNIX® file system that is suggested to be used instead of the Hierarchical File System (HFS), beginning with z/OS V1R7. Therefore, in z/OS V1R7 an official migration tool, BPXWH2Z, is delivered with z/OS to support installations in replacing HFS with zFS.

    This Redpaper describes and provides an additional HFS to zFS migration tool, named MIGRTOOL, that has been created as an alternative to BPXWH2Z. It provides more flexibility in many situations and offers options for how the migration should be done. In addition, it supports migration processing independent of the z/OS release, while BPXWH2Z is not supported in a z/OS system running at a level prior to V1R7.
