While there are a lot of great new features in later versions, as well as some bug fixes and security updates, I don’t think any of those are required to use the non-Flash dashboards. The updated dashboards should already be available in your console based on site version updates.
Your “Software Distribution” site should show two dashboards - one, the legacy Flash dashboard, and the replacement non-Flash version
If you don’t have a copy of the newer dashboard, you should check that your root server is properly gathering site updates.
