Upgrading to Jakarta EE 10 from an older version of Jakarta EE or Java EE can be a bit tricky and may require some extra attention to detail. But don't worry, we've got you covered!

In this series of articles, we'll explain everything you need to know before upgrading to Jakarta EE 10 and guide you to complete the upgrade successfully and in almost no time.

## Types of challenges

The challenges with upgrading to Jakarta EE 10 or to Eclipse GlassFish 7 fall into these 3 main categories:

* Changing the `javax` package prefix to `jakarta` requires updating all references to the old packages
* Obsolete annotations may need to be replaced with alternative annotations
* Rewriting code that uses removed APIs, which don't have straightforward alternatives

All of the above applies not only to your codebase but also to all dependencies used by your application.

## Existing tools to automate upgrade steps

Fortunately, many of the challenges can be automated using free and opensource tools like [Openrewrite](https://github.com/openrewrite), and [Eclipse Transformer](https://github.com/eclipse/transformer). These tools can save you time and effort when upgrading to Jakarta EE 10, allowing you to focus on other important aspects of your application's development.
