IBM i 7.1 was launched on April 13th 2010 and is the longest supported release of any IBM i midrange platform in the family history since the birth of AS/400. Before now, IBM i 7.1 had support for 2,929 days, against an average of 1,436 days across 25 releases since June 1988 when the AS/400 was launched. With the proposal that 7.1 will enjoy another support extension, this time of two years, we will have seen an incredible 4,755 days of support.
Here's a chart originally published by IT Jungle that details the release cycle:
Alison Butterill, IBM i office manager said of the proposed extension, "We have a number of clients who have not yet moved for a variety of reasons, some of the reasons for customers staying with IBM i 7.1 are due to applications, some are due to support for peripheral devices they need.”
Utilities 400 are committed to supporting our IBM i customer base on multiple levels of IBM i OS. Indeed, we still will have a partition on our development box that runs on v5.3. So, if you still have a box that's over 15 years old, we still have iterations of our solutions that can support you.
