The last two Java EE versions are probably two of the biggest ever, so WebSphere has gone through a lot of change in version 7 and now version 8. With support for WebSphere 6 dropping, companies going from 6.x to 8 may have more challenges in performing the code migration than first expected. As much as the goal is to minimize code changes and risk during the migration, we’re finding more issues to deal with when companies compile code against WebSphere 8 API and JDK creating the need for more troubleshooting.
Our team works through three major stages of setting an effective foundation for WebSphere 8 migration (which includes activities like planning, training and setting business priorities), conducting the core migration, then conducting a value migration through code or administrative enhancement.
However, you still need to make the migration happen first, so here's what we bring to the table:
Some companies want to migrate simply and at the lowest cost, others want to find ways to further reduce long term cost and make better use of WebSphere. In these cases, especially in this version of WebSphere, if the company has not yet looked at its applications, it’s a good idea AFTER the migration to look at the application architecture to see if it can be simplified or improvements made which improve the service level of the application by making:
Optionally, start to use Java EE 6 API in application code for easier development and better manageability:
This final process is we call the 'value migration'�because it's here that companies begin to simplify since once the upgrade is done, you need to drive value. This comes from looking at the way development is done and re-crafting the development playbook. Beyond uncovering features, teams need to internalize the use of features and demonstrate business value. It’s a process of facilitation, revisiting development processes, and looking closely at where feature sets can be deployed within in the portfolio to do administrative enhancements like:
We're not sure if your management also feels the pain, but we'd like to follow-up. Please advise.
