Reviewing software PTF (fix) requirements
Before you begin the IBM® i installation process, make sure that your system is ready by reviewing your requirements for program temporary fixes (PTFs).
- Finding the latest PSP information
Keep informed on the most recent information about conditions that might impede your IBM i software installation process. - Analyzing fixes you currently have on your system
A fix cross-reference summary list enables you to analyze the program temporary fixes (PTFs) and Licensed Internal Code fixes you currently have installed on your system. - Installing PTFs and analyzing your system for object conversions (V5R4 to IBM i 7.1 upgrade)
When or after you upgrade your system from V5R4 to IBM i 7.1, conversions occur on program objects in libraries, Java™ programs in directories, spooled files, and integrated file system names in file systems that are not case-sensitive. - Permanently applying program temporary fixes (PTFs)
Temporarily applied PTFs require a considerable amount of disk storage space. Follow these procedures only for IBM i products and temporarily applied PTFs that you have verified on your system. - Adding fix support for currently installed licensed programs
IBM licensed programs that are installed on your system are not automatically supported after an IBM i upgrade to a new release.
