You are correct that the new interface will take sometime to get used too. Also, the way that you do queries is a whole lot different. We won't go to the new version until sometime next year. I usually prefer to wait for the first patch before moving to any new software versions. In my opinion, it is better to wait for the bugs to be fixed.
I do plan on install the released version on a test server in the next month or so. This will allow me to learn the product and get familiar with it.
I'm certainly not moving to it yet, but I set my test server up this morning. I keep right-clicking things out of habit. 😉
I'm currently wondering why VSE850 is deploying to the test machines when I haven't set up a deployment task yet. Also, the reports seem to be blissfully unaware of machines that don't have an agent. It'll all become clear in time, no doubt.
