Hi all. Whilst this may be my fault I thought I’d post to prevent others making the same mistake. So, I enrolled in the program and downloaded the feedback assistant and the other required packages. I had a message in the app store to download and restart to install the beta. So I therefore partitioned and connected a separate drive specifically for this. Clicked 'download and restart' and the update downloaded. I waited for the screen to appear that allows you to choose an install destination, it didn't appear!!! DB2 wrote straight over my working install. It’s a two week old clone so it’s not the end of the world. Please be aware all.
