Jim, if you don't want to lose your WIN 7 options, you may want to consider setting up your DAW with a double boot.... Basically, you create a partition in your hard drive and install win 8 in your second partition. On boot up, the system will ask you to chose, and so you can use your DAW in win-8 mode.... However, that also means you may need to make your plugins and v-instruments available on your second Sonar installation. Also, make sure you have access to win-8 drivers for your hardware.
