We are currently hitting among ourselves to see if there is migration
tool/process in place to convert a VB.NET code base into ROR.
Essentially, our product is currently a desktop version and one of the
options for us is to adapt ASP.NET. However, we wanted something more
elegant - ROR. Any thoughts, rants, suggestions would be GREATLY
appreciated. Thanks in advance.
I don't know how this will work for you, but if I were doing this, I would sit down with the existing app and write cucumber stories (http://cukes.info/) that describe it and implement to make the scenarios pass. What that implies is that you will:
1. Install rails
2. Create a rails project
3. Install rspec and cucumber gems
4. Learn as you go how to use them
As far as I know there is no VB2Rails tool. But the benefit of creating the acceptance scenarios in cucumber and implementing to make them work is you wind up with a really good set of tests that will help keep your app stable. I'd also recommend reading the rSpec Book (http://www.pragprog.com/titles/achbd/the-rspec-book), currently in beta.
The test-first religion is an opinion shared by many in the Ruby community. Your mileage may vary.
Hope this is useful info.
