IBM i PTF Guide, Volume 19, Number 10

Technical Refresh updates have been a boon for the IBM i base. They have allowed IBM to keep adding features and functions to the current IBM i operating system releases without in any way breaking compatibility with the hardware levels and application software that runs on them. But you have to be careful about falling behind with the Technology Refreshes.
To be specific, as we explain in the TR tab in the IBM i PTF Guide, while the Technology Refresh updates do not happen that often, but when they do, this tab has all of the information that system admins help them figure out how to apply them. The left hand column has the PTFs listed and the links to the Wikis on the right tell you what is in the refresh.
One important note: You have to be aware that if you are two or more Technology Refreshes back from where you want to go — so, for instance, if you are on TR8 and the cume will apply TR11 — you must consult with IBM Support first. You may need to order the Resave and “slip the LIC” before applying the cume, which means you have to install the update to the Licensed Internal Code (LIC), and then apply the PTFs. This usually results in a machine having to be taken down on a Sunday afternoon and brought back up again after the LIC is updated.
Because of the complexity of doing that, if you are on a IBM i 7.1, you can accomplish the same thing by moving to IBM i 7.2 or 7.3. So if you are down level on the TRs, think of moving ahead to the latest release.
Good luck applying your patches this week, and we will see you next week with whatever IBM does. Here is the archive of the IBM i PTF Guide:
