DB2 10 for z/OS has been the most rapidly-adopted release in DB2′s history, with IBM stating that roughly twice as many customers upgraded to DB2 10 during it’s first two years of availability then they would normally expect to see. There are some very good reasons for that impressive adoption rate, mainly centred around the significant CPU savings and virtual storage enhancements which have delivered significant and early benefits for many customers (please see our downloads section for further information on the technical and business benefits delivered by DB2 10 for z/OS)
However, there are still customers that have yet to make the leap to DB2 10 for whatever reason. Those of you still on DB2 V8 (I’m not even going to mention V7 users as that went out of support nearly six years ago) have a great opportunity to leapfrog DB2 9 and use the IBM-supported “skip migration” feature to upgrade directly from V8 to V10. We’re currently working with one customer undertaking this journey, and it’s a great opportunity to be able to catch up with IBM’s DB2 release schedule if you’ve fallen behind for operational or budgetary reasons. DB2 10 should remain in service for at least another 3-4 years, and customers that successfully finish their DB2 10 upgrades during 2014 should still have time to schedule and complete an upgrade to DB2 11 while that release is the most current available.
For those of you on DB2 9 for z/OS, you’ll hopefully already be aware that the end of service date is now less than four months away, on 29th June 2014. You’ll also be aware that there is no skip migration support for upgrading directly to DB2 11, so you’re going to have to get to DB2 10 first. Ideally you’ll have your DB2 10 upgrade project well under way at this point, and scheduled to complete prior to the end of service date. If not, be prepared for some tough decisions regarding extended support fees when July comes around. If you need help with your DB2 10 migration project, please take a look at our DB2 10 Version Migration Services – we might be able to save you time and money.
Finally, it’s always good to keep IBM’s Software Support Lifecycle page for DB2 handy in your bookmarks list. This lists the General Availability (GA), End of Marketing (EOM) and End of Support (EOS) dates for each DB2 release, and should be one of your main inputs when planning your DB2 release strategy.
