The products, at the moment, are new and there should perhaps be support for the older version of the protocols. While I know that they have the new versions, which are actually needed, I don't believe they have that capacity when it comes to any integration with older systems. This is because I believe us to be more advanced nowadays, with what they are doing for the roadmap of new technologies.

I think rules engine processes and BPM processes should be improved. I think they must accommodate the future of the communication between systems and that is related to web services and the like. 

I am not satisfied with the solution because it takes too much effort to migrate and add new information. The migration could be easier. There's a lot of rework that needs to be done if you go to a newer version.
