And I’m going to assume that your NIM master is already running AIX 7.1 with the latest latest technology level (TL) and and service pack (SP) applied. Just as I did in my previous article I’ll assume you already have a NIM master in your environment. This reduces the processing overhead on the LPAR and minimizes the performance impact to the running applications.įor customers with a large number of AIX systems, it is also important to note that the nimadm tool supports migrating several clients at once. After the migration is finished, the only downtime required will be a scheduled reboot of the system.Īnother advantage is that the actual migration process occurs on the NIM master, taking the load off the client client logical partition (LPAR). All of this can be done without disruption to the client (there is no outage required to perform the migration). For example, a system administrator can use nimadm to create a copy of a NIM client’s rootvg (on a spare disk on the client, similar to a standard alternate disk installation alt_disk_install) and migrate the disk to a newer version or release of AIX. ![]() The nimadm utility offers several advantages over a conventional migration. I’ll also offer some general advice and tips. In this article, I’ll provide a brief guide to migrating both AIX 5.3 and 6.1 systems to 7.1. Admittedly the steps are almost identical. In this article I’ll briefly cover that same process but this time migrating to AIX 7.1. I’ve discussed using nimadm to migrate to AIX 6.1 in the past. I encourage you to read the >AIX 7.1 and 6.1 Differences Guides (IBM Redbooks® publications) to find out more – see the Resources section. Newer releases of AIX include a multitude of new enhancements, improvements, features and performance boosts. Of course there are other pressing reasons to migrate as well. You can find more information on versioned WPARs. These special systems are known as versioned WPARs and are only supported on POWER7 hardware. This will allow you to continue running your legacy applications on AIX 5.2 or 5.3, however they will run within an AIX 7.1 WPAR. If you have IBM POWER7® hardware, you might want to consider AIX 5.2 and 5.3 Workload Partitions (WPARs). This will help some customers in the interim while they migrate their systems to AIX 7.1 or 6.1. IBM is offering extended support for a limited time for a fee. IBM support will no longer be able to help you.ĪIX 5.3 officially went out of support on April 30th 2012. If problems arise on an older version of AIX you are most likely going to be on your own. ![]() If you are running an older version of AIX, such as 5.3 or earlier, you should already be aware that these versions are no longer supported by IBM. One of the most important reasons to migrate is support. Why should I migrate?īefore I discuss how to migrate to a newer version of the IBM AIX® operating system, let’s review why you should consider migrating at all.
