Migration of WebMethod from 6.0.1 to 6.5

Hi all,The discussion topic is not new but I haven’t got the right response for the existing threads. So I am starting it again.I am new user of WebMethods and have got training on version 6.5.Now I want to migrate my application from version 6.0.1 to 6.5I have found some threads discussing this requirement and I have got the little bit idea. But not able to start as there is no defined way to carry out the task. I would really appretiate if someone guide me for the same in terms of the document or any link describing this task.In the above task I am going to migrate the following components:1)Developer2)Models3)Broker4)Monitor5)repoV36)repo server and databaseAlso there are some adapters which would be changed as per the version upgrade modification.Thanks and Regards,Shantanu
