ABSTRACT
Upgrade and migration are common jargons in tech enterprises, and while these are necessary advancements to keep systems competitive and resilient, the journey to get there is rarely easy.
This whitepaper is a testament to that reality. Manuals and technical documentations are designed to tell us how to attain a specific outcome, but what it does not tell you is about the number of roadblocks, surprises and hard-won lessons you’ll encounter along the way.
This whitepaper breaks down the end-to-end process of migrating from IBM Sterling OMS on JDK 8 to IBM Semeru JDK-21. It is not just a technical manual, but a thorough and honest account of every stage involved; the planning, the execution, the challenges that caught us off guard, and the critical things you need to know before you even begin. Throughout we have made a deliberate effort to present this journey in the clearest, most accessible language possible so practitioners at every level can follow along and learn from our experience.
Lastly, the goal of this document is not to serve as a product brochure or a sales pitch. It is a guide by practitioners for practitioners, people who are about to roll up their sleeves and do the work.
If that’s you, you are in the right place.
