How to "copy" system image to new server
 
I have Red Hat 9.0 running on two servers. It is up to date on all patches (at least as up to date as possible since Red Hat no longer supports this version). Neither of these servers support RAID. I had a disk crash and was able to restore from TAR (TGZ) Backups.

I have set up a new server which supports RAID and now want to move a mirror image of the old server to this new one. I have tried setting up Red Hat 9 on the new server and then copying the TAR Backups from the old server. Since I want to pick up all of the Red Hat Updates, I copied all of the mountpoints.

The new system will not boot, but hangs on the GRUB Command.

I am assuming this problem is caused by the different disk layouts. Is there any way to fix GRUB so it will boot?

If not what is the best way to create a mirror of the old server?

a blind copy of everything will normally get your through, you might just need to reinstall grub into the mbr.

Thanks for the suggestion, but there seems to be more of a problem than just the boot loader. When I try to bring up the system with the Red Hat CD to reload GRUB I get a message that there is a problem with the swap file and to reboot the system. I can bring the system up from the Red Hat CD in Rescure Mode.

I have created blind copies of the filesystems and used them to restore the system on which they were created. I have had no problems with that but the problem occurs when I try to load them down on another system.
