Your choice since 7.2 has been one of two consoles, HMC or LAN Console. This prevents any conflict between the existing console and the Operations Console. If you are upgrading to 7.3 and you want to replace an existing console with a LAN attached Operations Console, upgrade the system before you migrate the console. The IBM i Access for Windows client doesn’t need to be removed from the PC but be aware the IBM i Access for Windows console will not continue working if the system is upgraded to 7.3. Note: The LAN console feature in the IBM i Access for Windows client will work for a D-mode install because SSL ciphers aren’t used during the D-mode IPL but on the following A-mode IPL the IBM i Access for Windows LAN console will fail to connect. You must upgrade to the new Java based Access Client Solutions product before upgrading to 7.3. This release is no different but you need to go another step. It has always been the recommendation that administrators upgrade the LAN Console software on the PC being used as the console prior to upgrading the OS. While we are on the subject of hardware, if you are using iSCSI IBM i 7.3 will not support iSCSI connected System x hardware, as that product has been stabilized.
Also, IBM i 7.3 isn’t supported on the IBM Flex System p260 and p460 Compute nodes for POWER7 or POWER7+ (Make sure you understand this is just IBM Flex Systems), nor Blades PS700, PS701, PS702, PS703, or PS704. In addition, Power6 BladeCenter models JS12, JS22, JS23, and JS43 machines can’t run 7.3. IBM i 7.3 is not supported on Power6 systems.
Every company’s IBM i environment is unique, and careful consideration and planning must be done for each upgrade to ensure there is no interruption to the business. While IBM i 7.3 contains many cool new features and functions, the upgrade has several points that you need to be aware of. These are a few of the items that I want to bring to your attention, and certainly not all the concerns that must be examined before an upgrade. We want to bring to your attention a few items and pre-requisites that you need to consider before you start your upgrade to 7.3. Reading the IBM i Memo to Users and the upgrade guide will help ensure you are on the right path to a successful upgrade. As with any upgrade, the success is in the preparation.
