We are planning to create a new instance and migrate the application to the new instance.However, we would be using the JBOSS application server instead of Tomcat app server which is being used in the existing environment. My queries are as follows: - Is there any issue that can be anticipated due to the change in app server for the new environment migration?- What is the pros and cons if we do an exact schema to schema copy and configure the JBOSS application server to connect to the schemas in the new database?- What is the pros and cons if we create new schemas and migrate the application by taking RAPs?

You need to take care of few tables that are specific to nodes. Like search functionality and all. 2) Pros: It will be fast. Cons: Few tables are node specific table and have node related data. You might not want those to take to new environment. 3) Pros: more fool proof. Cons: it require more effort.Coming to DSM and NBAM : Cassandra uses temp directory to have decision data store. May be you need to keep that in mind while doing so.
