Skipping a release
If you plan to skip an IBM® i release, such as performing an upgrade from V6R1 to IBM i 7.2 and skipping IBM i 7.1, you need to be aware of changes from the skipped version and release that could affect your programs and system operations.
If you are skipping a release level of IBM i, you should review the Memo to Users for the release that you are skipping. This will ensure that you are aware of software changes that occurred in the skipped release that could also affect your programs and system operations.
