Clean Up Data Sets from the Previous Version

After using the latest version for some time, we recommend that you clean up the previous version data sets and folders and free up the DASD.

Review the MSMPWIPE job closely before removing the previous version contents.

You can remove previous version mounts from the system depending on how you set your previous version installation preference for single or multiple mount file systems.

• The previous version is installed in a single file system. The msminstall, msm, msmruntime, msmtmp, and mpm folders are created under one mount file data set. Then, you can remove the msminstall, msm, and msmruntime folders from UNIX System Services (USS).
• The previous version is installed in multiple file systems. The msminstall, msm, msmruntime, msmtmp, and mpm folders use individual mount file data sets. Then, you can remove the msminstall, msm, and msmruntime folders from USS, delete the related mount file data sets, and remove auto-mount entries from SYS1.PARMLIB(BPXPRMxx), if included.
