Yes, you are.  However, I recommend that you plan every step carefully,
so that you don't wind up with an unbootable system.  Make sure that you
have renamed the "local" LVM volumes, the fstab entries and anything
that might depend on those names. ( some things can break, but you had
better make sure that you can boot -- by the way, what do the entries in
grub.conf refer to? )
