Major update of web services stack was performed between EAP 6.4 and 7.0 (from 4.3.5.Final to 5.1.1.Final). The current version of Migration guide, chapter 4.3. Web Service Changes is far from being complete from my point of view.

Summary of significant changes can be found in these docs or links:

1. https://developer.jboss.org/wiki/JBossWS5MigrationNotes
   • all changes should be mentioned
2. Complete drop of support for Spring https://issues.jboss.org/browse/JBWS-3885
   • as a consequence Spring descriptors (cxf.xml and jbossws-cxf.xml) are no longer used, users need to migrate these settings to code or jaxws-endpoint-config.xml (jaxws-client-config.xml)
   • more info can be found on comunity documentation https://docs.jboss.org/author/display/JBWS/Apache+CXF+integration#ApacheCXFintegration-BuildingWSapplicationstheJBossway
   • examples of possible old approach and new approach of configuring WS-RM
     • https://access.redhat.com/solutions/176063 ++ sample of cxf.xml
     • examples of new approach https://docs.jboss.org/author/display/JBWS/WS-Reliable+Messaging ++ sample usage of WSRM with RMStore without Spring
3. Endorsed dirs approach is no longer used https://issues.jboss.org/browse/JBWS-3927, users need to ensure the proper order of dependencies (If depending simply on jbossws-cxf-client they should be fine)
4. Added ability to consume jboss-webservices.xml located in META-INF of EAR archive
   • https://issues.jboss.org/browse/JBWS-3865 ++ https://docs.jboss.org/author/display/JBWS/Advanced+User+Guide#AdvancedUserGuide-Configurationthroughdeploymentdescriptor
5. Release notes for each Final version from EAP6.4 to 7
   • https://issues.jboss.org/secure/ReleaseNote.jspa?projectId=12310050&version=12327611
   • https://issues.jboss.org/secure/ReleaseNote.jspa?projectId=12310050&version=12326872
   • https://issues.jboss.org/secure/ReleaseNote.jspa?projectId=12310050&version=12327684
   • https://issues.jboss.org/secure/ReleaseNote.jspa?projectId=12310050&version=12328920

Also there could be a note that there are several significant changes in CXF and WSS4J projects and users should consult apropriate migration guides when using some special features or encounters problems during migration. (However, these links aren't guaranteed to be consistent, they already changed this year, so we could avoid hardcoding them)
