===Introduction===

This HowTo describes a simple way to move your SMEServer system to another set of hardware by just moving the hard disk.

<pre style="color:red">
Moving the HardDisk to new hardware usually works without any intervention, but sometimes the boot fails with a "Kernel Panic". 
In this case you should follow these steps.</pre>

This technique seems to work for SME8, tested on SME8.0b7, no guarantees on any other version.

===Backup First===

Never do anything like this without a viable backup.  If you have a Raid 1 system with 2 hard drives, then check you can boot from either of them, and then keep one safe in-case the procedure fails.  If you have a USB hard Drive backup or some other form of backup, then I recommend you make sure it restores properly before you start.

===What to Do===

* Boot up the "old" system and run:

 uname -r

this will give you the name of the current Kernel.  ''It is needed below''.

*Remove the hard Drive and load it into the new system
*Boot from an SMEServer ISO CD into rescue mode, by typing "sme rescue" at the initial prompt.
*Select to enter rescue mode in Read/Write mode
*Type in the following code:
 chroot /mnt/sysimage
 cd /boot
 mv initrd-YOUR_KERNEL_VERSION.img initrd-YOUR KERNEL VERSION.img.old
 mkinitrd initrd-YOUR_KERNEL_VERSION.img YOUR_KERNEL_VERSION
*Then reboot and if it has worked, then the system will boot normally.
*If not, then you'll have to think again, or use the longer way as [[Moving_SME_to_new_Hardware|here]] or using a backup as [[http://wiki.contribs.org/Category:Backup Category:Backup]]

This came about through a question I posted on the Forum, and was quickly answered by Stefano, many thanks to him.
