Re: [PLUG] BEST way to move all contents from one server to another

[James Barrett <jadoba@jadoba.net>]

If you want to duplicate the entire system, file-by-file, then you can
try the following:

* Boot the remote server with a Live CD, or a live linux system over
netboot.  Secure the running instance, set a root password and start
SSH, then give it an IP address.
* Partition the remote system drive as necessary, and set up LVM and
format as necessary.  Mount the partitions/volumes on the remote
system.  If using a separate boot partition, then create a /boot
mountpoint on the root volume and mount the partition to it, and
similarly for all separate partitions (/tmp, /var, /home and so on)
* Use rsync to transfer the local system to the remote system, but you
absolutely must exclude the following directories:

 /sys
 /dev
 /proc

* Also, be sure to exclude any network shares, or other things you
don't want to transfer over.
* You may as well want to exclude /tmp or /srv ... or maybe not, it
depends on the intended use of the system, and it's up to you.
* The following command may suffice:

rsync -av --exclude="/dev/" --exclude="/sys/" --exclude="/proc/" /
root@86.75.30.9:/

* "-a" is for 'archive', "-v" is for 'verbose'
* Don't use that IP address, that's Jenny's server...
* After this, you'll need to set up Grub/LILO or whatever else as
necessary, so keep the LiveCD handy at the remote end.
