title: Migrating Java 8 project to Java 11
body: <p>We have a repository built using Java 8. There are multiple rest services within the repository. We want to migrate to Java 11 and trying to figure out the best way of doing this. We are considering doing module by module. For example changing one service over to Java 11 while the remaining are still Java 8. We are unsure if Maven supports this?</p>
