Preventive Service Planning
Abstract
This document provides guidance for upgrading the IBM i operating system to 7.5.
Content
This document can be used as an index for topics related to upgrading an existing IBM i environment to IBM i 7.5.
IBM i 7.5 requires Power 9 or later hardware and valid source releases are IBM i 7.3 and IBM i 7.4.
The IBM i 7.5 Licensed Internal Code requires more storage on the load-source disk unit than IBM i 7.3 Licensed Internal Code. To upgrade to IBM i 7.5 Licensed Internal Code, all systems will require up to approximately 8 gigabytes of system ASP free space before IBM i 7.5 can be installed. The upgrade will stop during the installation of Licensed Internal Code if this space is not available.
If upgrading from IBM i 7.4, the required free space was already checked during the prior release installation.
Ordering and Downloading upgrade media:
IBM i 7.5 can be ordered by contacting your IBM marketing representative or your IBM i business partner that provides support. It can also be ordered using the Entitled Systems Support website. For assistance with the entitled systems support website email wwswkeys@dk.ibm.com or call the number for your country found on ESS Support.
The upgrade media can be downloaded from the entitled systems support website. It will come down as zip files and will need to be decompressed before being transported to the IBM i partition that will host the media. The installation media will be placed into an image catalog either on the IBM i partition that will be upgraded or an IBM i partition that will host media for network installation using network file system.
PTFs required to upgrade:
There are PTFs required to upgrade from IBM i 7.3 or IBM i 7.4 to IBM i 7.5. These PTFs are documented in Required PTFs for Upgrading to IBM i 7.5.
Memo to Users:
Memo to users describes the changes that might affect your programs or system operations. Read the memo to users document to ensure system requirements are met before an IBM i installation or upgrade. If you will be upgrading from IBM i 7.3 directly to IBM i 7.5, you should review the IBM i 7.4 memo to users in addition to the IBM i 7.5 memo to users.

Planning to upgrade to IBM i 7.5 (Software):
This topic provides list of products and functions not supported on IBM i 7.5. Plans should be made to replace or discontinue use of these products and functions prior to upgrading to IBM i 7.5. If you will be upgrading from IBM i 7.3 directly to IBM i 7.5, you should review the IBM i 7.4 discontinued product listing in addition to the IBM i 7.5 discontinued product listing.

IBM Pre-Upgrade Verification Tool for IBM i
The IBM pre-upgrade verification tool for IBM i was developed to help ensure a successful upgrade. The tool ensures that the required pre-upgrade steps have been successfully completed and flags the steps that were missed or completed incorrectly. The person performing the upgrade then has the opportunity to successfully complete the required steps. The tool does not automatically perform the corrective actions.
Download, installation and usage instructions are found in document IBM Pre-Upgrade Verification Tool for IBM i.
In order to ensure all of the checks are up-to-date and enhancements included, it is important to always use the current build level for the tool. It is recommended that you regularly check for updates.
Data Migrations:
An IBM i data migration is the process of moving data from one system or logical partition that is running IBM i to another system or logical partition running IBM i. When migrating data between systems, the source system and the target system have different serial numbers.
