What happens when I update, it updates to 6. Or is there also a release of 5.2 available? Because a lot changed in 6...
I think that if you check out the Upgrade notes to Servoy 6.0, you'll notice that there isn't so much changed that causes you to make changes to your solution: http://wiki.servoy.com/display/DOCS/Upgrading+to+Servoy+6.0
Servoy 6 offers loads of new features and better Developer tools, but just getting your solution up and running in Servoy 6 should be very straight forward. Only when you want to reliably use some of the new features do you need to do some work adding JSDoc to get rid of warnings, but having those warnings doesn't mean you cannot use a lot of all the other new features.
