Sorry for cross posting.
I now seem to GN version 2.7 snapshot revision r8695 with ANZMEST
schemaplugins revision r8650.p migrated and running on the new server.
I am now debugging or documenting the errors.
When I start up GN I get the following in the catalina.out file:
validateJarFile(/data/jakarta/geonetwork-asdd/webapps/geoserver/WEB-INF/lib/servlet-api-2.4.jar) - jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending class: javax/servlet/Servlet.class
Is this an issue? Is it my setup or is it something that GN 2.7 does?
