WFLYEJB0450: Entity Beans are no longer supported

Hi Team,
We are doing migration of one of the application which was running earlier in JBoss 6.0.0 FINAL and JDK 1.6.

Now when I am trying to migrate the application to the new JBOSS 7.3.0 and Amazon Corretto 1.8, we are getting the below error:

Please provide solution to the below issue:
