I'm trying to do an upgrade from 7.8 to 7.9. I got a clean install of 7.9 running using the Configure Script then I tried migrating the data from our 7.8 instance into the 7.9 install. I followed the migration guide (forum.appian.com/.../Migration_Guide.html. I got through starting up the engines and the search-sever but can't seem to successfully start the application server. Jboss seems to blow up after it installs the plugins and consistently breaking with the following error.
