Cloning a Linux Server

[Gordon Chapman]

We currently have a web server, running apache/tomcat and want to replace it
with a higher spec machine, we would normally use Norton Ghost to make an
image but the problem I have in this instance is

Current machine is Single CPU machine, with IDE disks
New machine is Dual processor, with SCSI disks

Can somebody point me in the right direction as to the best way to achive
this

Many Thanks

Boot the new box from a linux rescue CD of your choice.

Build your new SCSI filesystems as you wish.

Allow tar/rsh, tar/ssh, rsync, rsync/rsh, rsync/ssh, or whatever is
available from the rescue CD, to use your local network to transmit the
live system image to the target machine and overlay it on your new
mounted filesystems. Or stuff it onto a CD and mount that.

Edit your new /etc/fstab appropriately for your new OS.

Update your lilo.conf or grub.conf to create a new MBR wherever you want.

Reboot and take out the CD.

Indeed.

I would add, however, that if you are doing this a lot it may be worth
your while just turning everything on as a module. This way you have a
kernel that works with anything. 1 image that fits all! :)
