[CentOS] grub To grub2 Migration

I'm trying to move to CentOS 7.  One of my concerns is how to make the 
changes to grub that supports booting from either of the disk partitions 
that make up /dev/md0 (/dev/sda1 and /dev/sdb1) or whatever it would be 
under CentOS 7.

Is there some document or tutorial available on making the move from 
CentOS 6 to CentOS 7?
