So we want to take all these and migrate to the new server to reflect this. Old server also had FC6. So we are doing a dump of the old server to the new hardware.
Right, so are you looking to move data held within a mail server, or disks between two machines? if you can decide on an ideal strategy we can try to work with that.

Hi acid,
We are not moving the actual disks to another machine. We just bought a new server with a raid array. We are taking the information/partitions from the older server and want to migrate them over to the new server.
I am looking for a way to move the disk image from the old server to the new one.
It's tricky but doable. You will need a good rescue CD like Knoppix or Sysrescd. This is what I recommend:
-create the /boot, /, swap and any other partitions on the new server.
-tar each partition individually on your old server.
-dump the tar on the new partition of your new server.
-modify grub mbr and menu to reflect the new partitions.
-modify your fstab file.
-you may need to modify the initrd for drivers for your new server. Tha't another paragraph to itself. Most of the times you don't need to modify the initrd.
-restart and cross your fingers; rinse and repeat.
