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