Migrating from one machine to another - any convenient way?

[Versusnja]

Hi!

I'm running an Ubuntu Hardy server.
LAMP + samba + proftpd + mailserver + some other stuff

Is there any convenient way to migrate from one server to another more powerfull machine?

Can I simply put a HDD into another box?

I will appreciate any bit of information.

Of course you can but make sure of the hardware compatibility of both(old and new) boxes are same...Because you may experience problems with installed software/drivers...And also hardware plaforms like i386 and amd must be same...

You can use the dd command to transfer the image. here is a link on how to do the command:

Thanks a lot. This is VERy helpful and exactly what I need.

But what I'm worried about is shouldn't I recompile kernel or do something additional hardware configuration for image to work on a new machine?

Do you think this will work "out of the box"?

The only thing you will need to change are your block id's on the new system. I would remove the block id's used in your fstab file and use the standard /dev/sd? configuration until you can boot off of the new system and then update them. You can find the block id using "blkid" on the new system.
