Interesting... can I do that with the preupgrade from 6.5? And I *rarely* see grub updated....
I'm not familiar with preupgrade, but I would guess that this method wouldn't work. (Actually I'd be somewhat surprised if it were possible to do an in-place upgrade from CentOS 6 to CentOS 7 and get a properly functioning system; the differences between the two are so large.)
I pretty much always do side-by-side installs and then move data and configurations over.
Configs from GRUB and GRUB2 can coexist in same /boot tree, I managed to install GRUB2 over GRUB and configs of GRUB were NOT affected. Reinstalling GRUB from 6.x should do the trick and no GRUB2 update should mess with functioning GRUB1.
