title: How to migrate Java app from Tomcat 7/8/9 to Tomcat 10
body: <p>Tomcat 10 came out recently and trying to simply deploy the apps. Since the Java EE 8 using javax.* package name spaces and Tomcat 10 uses Java EE 9 which using jakarta.* name spaces, it is difficult to migrate from tomcat 9 to 10. Is there any way or tool to do that? I think this is the same for tomcat 7/8 too.</p>
