The Many Roads to DB2 10

As most of us are aware, the clock is ticking and the countdown to get off DB2 Version 8 is getting closer and closer. Many DB2 professionals are currently going through stressful migrations as they are struggling to meet the deadline of April 30, 2012.

As IDUG introduced their "DB2 10 for z/OS Upgrade Experiences," there was an interesting discussion about whether to do two migrations via DB2 9 to get to 10 or follow the skip migration path.

One thing that was pointed out was that unless your (or the company's) risk appetite would fit being an early adapter of a new release of DB2, you may have had no other choice than to go through the two steps. The fist migration from DB2 Version 8 to 9 would be purely based on normal software lifecycle needs with EOS being announced.

The business case for going through another software lifecycle shortly thereafter could then be easily justifiable based on CPU savings and all the nice new features being made available in DB2 10. Take a look at what was covered around DB2 10 for z/OS at IDUG in Prague and if you missed the DB2 Tech Conference in Prague, you may have a good justification for registering for the DB2 Tech Conference in Denver in May where a lot of DB2 10 topics will be covered as well.

Also keeping in mind that you will have to learn and adapt new features and functions in both DB2 9 and 10, so perhaps a step by step approach would be the right way forward considering all factors.
If you are unable to document enough value relevant for your company to support the DB2 migration sooner rather than later, it's important to keep in mind that DB2 9, EOS has been announced for June 27, 2014.

In any case, the great thing about migrating later in the lifecycle of a given release is that you get the benefit from other people's experiences, which may be documented as people have presented at an IDUG DB2 Tech Conference or things that are being discussed virally on DB2-L or specific forums. If you are in the midst of migration to DB2 10, please don't forget to share your experience to help other fellow DB2 professional using DB2 10 for z/OS Upgrade Experiences.
