So, the migration should not be an issue. Few tweaks here and there and – we were able to run the projects. Few Spring framework configuration files had to be updated (most probably because we should update Spring version, too). In general, the migration passed quite smooth.
Recently we have tried to migrate to the latest Java 8 version. In the company I work for, we have couple of projects still running under Java version 6. But, before that, I would recall important Java 7 features, which you may not had a chance to use, but could be quite handy. There are many web sites describing new Java 8 features in detail, I would like here just to briefly list them. But you will not be able to get advantage of the new features and new concepts without taking some time to explore and learn about them. Java 8 is backward compatible with previous versions.
You can jump in and start coding in Java 8 using your previous Java programming experience. Aside to this, Java 8 is a bigger milestone in the Java programming language history and brings Java development to a completely new level. The most obvious reasons for moving from Java 6 to Java 8 are new language features and security improvements. It is likely that those projects are implemented in Java 5 or 6 and are planned or already migrated to the latest version of Java. Many of us are working on Java projects which have started some years ago.
