To make the problem clearer, I have a project (using jboss 7.1.1) which was using jbpm 3 version. Now I am trying to upgrade jbpm 3 to jbpm 5.4 in my project, instead of using the whole jbpm 5.4 installer project.
My question is how to do this. My first confusion is where the initial sql scripts are to create associated tables in my database (I am using MySQL).
