I have a server that is remotely hosted and has a drive with over 48k
hours on it (and still running strong)...my hosting company is
providing a free replacement and I need to migrate everything over and
have the system come back up gracefully without any physical
interaction...other than one drive being stuck in the second drive bay
temporarily and the original being taken out and replaced with the
second drive when ready.

Here's what I have:

/dev/hda - 60GB old drive
    hda1        Boot        Primary   Linux ext3                          78.45
                            Pri/Log   Free Space                           1.04
    hda2                    Primary   Linux swap / Solaris              1074.00
    hda3                    Primary   Linux ext3                       58869.01

/dev/hdc - 80GB new drive
    hdc1        Boot        Primary   Linux ext3                          74.84
    hdc2                    Primary   Linux swap / Solaris               511.97
    hdc3                    Primary   Linux ext3                       79439.57

/etc/fstab
     /dev/hda3   /       ext3    usrquota,grpquota,errors=remount-ro   0 1
     proc        /proc   proc    defaults            0 0
     /dev/hda2   none    swap    sw                  0 0
     /dev/hda1   /boot   ext3    defaults            0 2

By my thinking...I should be able to:

mkdir /newdrive
mkdir /newdrive/{boot,newroot}

mount -t ext3 /dev/hdc1 /newdrive/boot
mount -t ext3 /dev/hdc3 /newdrive/newroot

rsync -av / /newdrive/newroot
rsync -av /boot /newdrive/boot

grub

grub> root (hd0,0)
grub> setup (hd1)

and then shutdown, pull hdc and put it in hda and fire it up.

What I'm uncertain of is the "setup (hd1)" bit....will this setup the
boot field in some way such that it will not work?

If the drives were the same, I'd feel comfortable using dd to simply
copy over the MBR, but since they are not, I'm worried about wrecking
my partition table.


Thoughts and advice are urgently needed. Thanks!!!
