Does anyone know of a way to backup a site running on omd built for 
RHEL6 and then restore that site to a system running the same version of 
OMD but for RHEL7?  I've got a few secondary servers that I'd like to 
reinstall with Scientific Linux 7.x but if the backup/restore function 
in OMD isn't going to play nice it's gonna make the upgrade a lot more
