Well, I thought I would try the reservation route but really wanted to get things going sooner. I was already signed up for the INSIDERS program running Windows 10 using VirtualBox on my MacBook Pro. I went to the insdier's site and was able to download the final version setup from there.
I did the upgrade to keep everything in place and things went very smoothly.
One thing to not is that the upgrade installation creates a Windows.old folder as well as the Windows 10 installation folders. You can run the Disk Cleanup program to free up a lot of space. I tried manually deleting them at first but they were protected by the System so using the App is the way to go.
So far so good.
