Re: Migrating RAID 0 from Ubuntu 11.x to 12.x
I don't think you need the last option. The --assemble --scan shouldn't touch any meta data or any data on the array.
What you should be careful about is running mdadm --create because that is used only once when the array is originally created and it destroys data in the process. Never use it on existing arrays.
Also, the live cd installer doesn't include the mdadm package and can't recognize the array during install. You can either boot into live mode, add the package and assemble the array, and only then start the installation with the desktop icon, or, simply install on another disk ignoring the array, and then add mdadm package and assemble it. You will also have to create a mount point for it and an entry in /etc/fstab.
I think you will also need to update the initramfs so that the array is assembled every time on boot, something like:
sudo update-initramfs -u
Darko.
