A Few days back we had a discussion about migrating the ESB to the new eventing component and realized that there are several things to be done in this space. We also need some features to be implemented in the eventing component before we can do a proper migration. So I think we should take this slow. And as Senaka has mentioned, if there are MT related issues etc, we better make sure that are properly dealt with first.
