I have a few versions of /etc/ backed up - most of what I ever need in a new install (physical or VM) is in there. The rest is somewhere in /home - but when installing clean after skipping a version of Debian, I prefer to move ~/.config/ to a backup location, before logging in the first time, then just customize till I get things reasonably the way I like - and I can always grep through my old .config just in case... So apart from a little command line mounting of old stuff occasionally, but in the new system, I always boot into my new system. SO, re your grub setup - and since you're now in your old install - you might configure old grub to know about the new install, and update grub to the HDD accordingly. In fact, I would also install a grub that recognizes all my installs, to BOTH HDDs! That way you can always boot into something. Other than that, as soon as I can start working in my new install, the better as far as I'm concerned. As a mountpoint, perhaps /media/wheezy for mounting your old root, or vice versa? Good luck,
