I am converting an application from VisiBroker 3.0 to VisiBroker 4.0. What are the issues that I must address? Where can I get more information about it?

We have recently migrated our project from VBJ 3.4 to VBJ 4.x. There are a variety of issues you would want to address depending on the VBJ features your application uses. You would need to exercise some migration paths like BOA to POA, package changes etc. Some VBJ 3.4 features have been deprecated/removed in VBJ 4.x. Eg: EventHandlers are no longer supported. Principal object is not supported. There is a chapter at the end of Programmer Guide for VBJ on migration from VBJ 3.x.
