Hi.
I’m not clear if there is any tool to do it. I think from V7 to V8 if there is one, but from V6 to V8 …
In addition, the differences are so great that what I recommend is to redo the application 100%

I’m sorry I can not give you another answer
a greeting

where can i get the documentation of vaadin version 6 and Spring 3.0, I could not find it in vaadin website itself. I want to know how redirection is taking places in between the pages.
