How to Migrate from Java 8 to Java 17+ Using Amazon Q Developer

Replatforming from Java 8 to the newer Java versions has proven to be a huge challenge due to potential compatibility issues and changes in language specifications.

Because of this, migrating from an older version like Java 8 would involve code modifications, which take considerable effort and rigorous testing.

Before diving deep into version upgrades for Java applications, let us first discuss what Amazon Q developer is and how it helps developers with application modernization.
