If you have moved IBM-supplied product libraries to user auxiliary storage pools (user ASPs), the installation procedures will not update the libraries.
To prevent this problem, ensure that IBM-supplied product libraries are in the system ASP before you start the installation procedures. The product libraries should remain in the system ASP. PTFs are not applied to product libraries that are not in the system ASP.
If you have duplicate IBM-supplied product libraries, delete the duplicate libraries before you start the upgrade procedures. The upgrade process fails and the new release does not install until duplicate IBM-supplied libraries are deleted.
