If you migrate from PE Version 1 or Version 2 to PE 3.2, installing the new filesets will completely replace some of the earlier release filesets, rendering them obsolete. The replaced filesets will be marked "OBSOLETE" in the object data manager (ODM) and lslpp by installp.
However, some directories and installation files will remain. Because these earlier filesets do not coexist or execute with PE 3.2, you should uninstall your old filesets before installing the new PE filesets, rather than installing the new filesets on top of the old. This will conserve disk space and reduce the chance for confusion over old fileset path names and executables.
Caution:
If you plan to uninstall the old filesets, do so before installing
the new filesets. If you attempt to uninstall the old filesets
after installing PE 3.2, you may accidentally delete some
needed files.
The following table lists the old filesets that need to be removed
before you install PE 3.2:
| PE Version | Filesets to be Removed |
|---|---|
| 1 |
pedocs poe poe_pcf vt xpdbx |
| 2 |
ppe.pedocs ppe.vt ppe.xpdbx |
You can use the lslpp command to check if any of the filesets mentioned previously are installed. For example, lslpp -l poe will tell you if the Version 1 POE fileset is installed.
To remove filesets you can use any of the following methods:
Use the Maintain Installed Software dialog found under the Software Installation and Maintenance dialog.
installp -u poe
The ppe.vt and ppe.pedb filesets are not supported in PE 3.2 and existing installations should no longer use these filesets. You should remove these filesets because the PE 3.2 installation procedures do not automatically remove or mark them as obsolete, or prevent anyone from using them. To remove them, you can use either SMIT, installp, or the PEdeinstall or PEdeinstallSP scripts.
