Hi Rick,
I should have clarified that it wasn't a server move so much, but a hard drive failure. They replaced our hard drive with a new one, and the image was Redhat 9, not 7.x. The physical machine didn't change. I did have backups and yes the my.cnf is the same. I've since made some changes, but I did check that out.
I'm really at a loss to explain it.
