    BPXWH2Z Migration Utility

    What is being removed or changed

    z/OS 3.2 is planned to be the last release of the operating system to support the BPXWH2Z migration utility. This utility was used to migrate data from Hierarchical File System (HFS) data sets to z/OS File System (zFS) data sets. Because HFS data sets have not been mountable since z/OS V2.5, this utility is no longer required.

    Required customer migration or upgrade actions

    Clients should discontinue use of BPXWH2Z and use the strategic migration utility BPXWMIGF, first introduced in z/OS V2.3. BPXWMIGF supports data migration from HFS to zFS as well as zFS to zFS and should be used for any remaining file system migration needs.

    PAGEDEL DELETE Option

    What is being removed or changed

    z/OS 3.2 is intended to be the last release to support the DELETE option on the PAGEDEL system command. PAGEDEL DELETE has been functionally superseded by PAGEDEL REPLACE.

    Required customer migration or upgrade actions

    Customers should transition all usage of PAGEDEL DELETE to PAGEDEL REPLACE. PAGEDEL REPLACE is the long‑recommended alternative and offers benefits such as reduced memory usage and improved processing efficiency.
