I would say it's between 8 and 9 - both versions are slotted, so you can install both at the same time. If you have trouble, you can reboot from a install cd/usb-drive and reinstall legacy grub. I never had any trouble with grub2 and I am using it since about 2 years, I think (at least no non-"handmade"-trouble ;) ). So I think it's easy. If you have a line for the init thingy in your grub.cfg it should use that or throw an error. If you use dracut according to a fedora-page you can add "rdshell rdinitdebug" to your kernel commandline and see dracut debugmessages and being dropped to a shell. maybe you could try that. Since I don't use dracut I'm not sure if it would mount a seperate usr. A quick google search seems to indicate that you have to do something manually: according to the last answer dracut tries to mount usr if init is a path in /usr - so you could create a symlink and add "init=/usr/bin/init" to your kernel commandline [1] - or use systemd (it should reside in usr, shouldn't it?).
