Migrate from vaadin 6 to 7 or migrate directly to vaadin 8

Hello everyone,

I’m planning to migrate our legacy web application from vaadin 6 to vaadin 7. We haven’t do that until now because some business constraints. This situation has change and right now, it’s mandatory for us to migrate to newer versions of the framework. Today is the release day of vaadin 8. The question is:

It’s better to migrate to vaadin 7 or make the migration directly to vaadin 8?

It’s important for us to be sure that the framework is stable enogh because our web application is a mission critical one and we need to minimized any bug or issue related with the framework. Any advice for this?

Thanks
