This section discusses how to migrate data from HFS to zFS. In all cases, the target file system can be version 1.4 as well as version 1.5. If all of the systems at your site are running at least version z/OS® V2R1, then it is recommended that you use version 1.5 aggregates for your new file systems.

Guideline: Do not use the HFS to zFS migration tool if you are migrating your sysplex root. To migrate the sysplex root, consider using the MODIFY OMVS,NEWROOT operator command. For details, see the topic Steps for dynamically replacing the sysplex root file system in z/OS UNIX System Services Planning.
