Much has been said about Oracle SOA Suite 10g (or JCaps) upgrades to 11g and how features map between both versions. There is also plenty of information online about this topic both official and unofficial. It’s not news to many that for example SOA Suite 10g is currently in extended support and product will enter sustaining support by the end of 2014 (I will explain more about what extended and sustaining support means later in the blog). However one fact remains truth: There are still many companies out there running platforms that are (or soon will be) in sustaining support, and that don’t yet have an upgrade strategy. I say this based on my own experience as I am currently helping several customers do exactly this.
Having said that, I wrote this blog in an attempt to give SOA experts, Integration Leads and Architects key pointers that can serve as inspiration to come up with a transformational approach when defining an upgrade strategy. Note that I am using the word “transformation” deliberately and I will explain why shortly.
Note that although this article is mainly related to the Oracle SOA 10g to 11g technology stacks, the approaches, tips and information provided in this blog should also be applicable when defining any technology upgrade. In fact, once 12c is more mature I will probably refresh this blog to cover 11g to 12c upgrades.
Following my key pointers to help you define your upgrade as a SOA Transformation:
1)Understand the product roadmaps and planning to move in advance
2)Take a SOA Transformation approach and not just a technology upgrade
3)Elaborate a SOA Transformation Roadmap
4)Understand current and future technology stacks and identify potential risks and challenges in advance
5)Define a service transformation methodology
6)SOA transformation also requires organisational changes and maturity
1) Understand the product roadmaps and planning to move in advance
This is one of the most important points and one that many have either failed to understand or have just ignored (hence why many companies still stuck in 10g and have no plan to upgrade yet). This is important because by understanding the product releases and features, release dates, and support lifeline you can plan in advance an upgrade approach and avoid having to do something tactically, in a rush and with limited budget.
Before getting further into this topic, it is critical that you understand the basics of Oracle product releases: Read the complete article here.
