Help Pls: System Upgrade: OLD=vista+dd10.0; NEW=Win7+dd11

Is OSS installed on the Vista drive? If not, then just proceed normally. If it is, I would recommend connecting the Vista drive by itself (disconnect the Windows 7 drives) and uninstalling OSS/DD. After that, reconnect the Windows 7 drives and finish normally. I assume you would make one of the Windows 7 drives the default booting drive.

If you're going to be using OSS, it's best to create a small partition just for it (or use a data partition) instead of installing it to an OS partition. You must do a Custom install of OSS to be able to select the partition OSS uses.

MudCrab, thanks for the response.

I just realized I mispoke in my last paragraph; I meant to say " DD10 not supported by Win7".

My concern relates to my assumption that to install the DD10 to DD11 upgrade on Win 7 I must already have DD10 installed on Win7. Your response implies I am wrong there, and can simply launch the upgrade downloaded exec file as a clean install, and that having the old serial # is all I need to complete the installation process of DD11 on Win 7. That indeed simplifies things. I will follow your advice wrt uninstalling OSS from the Vista/old drive system first.

Your advice re installing OSS to a small data partition is interesting. Have you tried it?

Thanks again for your help.

You can install the upgrade version with just the two serial numbers (one for DD 10, one for DD 11). You don't need to have DD 10 installed first.

Installing OSS to a non-OS partition is how I prefer it and how I use it. Think of it this way: If you have it on an OS partition and later restore that OS partition back to the state it is now, the OSS files will also be changed back and may not allow you to boot into your other operating systems. In my opinion, it's just better to keep them separate.

Thanks again, MudCrab.
