in work I have one hard disk and I install on it FreeBSD 8.2 AMD64 and I use Gnome and my motherboard is Asus and my CPU is Intel with 3GB of RAM , and I want move this HDD to another system because of motherboard error and broken motherboard , I can not find another mother board like this , and finally I find another motherboard with nVidia chipset and AMD CPU and , so I want move this HDD to new system , before I move to new motherboard with new chipset and new CPU , what I must do ?
I do not reinstal FreeBSD , and I want FreeBSD work for me with new mainboard and new CPU .
if I move HDD with FreeBSD installed to new motherboard and new CPU , what I must do ?
Do I need modify something ?
 
I've done this with vanilla FreeBSD install. Install on machine A and move disk to machine B.
It worked.
You may want to check your /etc/fstab for correct mount points on your new machine.
 
Unless you used a highly customized kernel there shouldn't be any major issues. Just move the drive to a new system and boot from it.
 
Disk device numbering and names can change. As mk points out, this can affect /etc/fstab, but it's easy to avoid if you use labels; see FreeBSD Labeled Filesystems.

Ethernet device names and numbering can change, too, affecting firewalls. If the system was built with CPUTYPE set, it will only run on a similar CPU.

Network/firewall settings may also need to be reviewed if the network card(s) in the new machine use a different chipset from the old machine.
 
Hard drive is cheap*. So I have two suggestions:

1) Fresh install 8.2 or 9.0 current on a new HDD and then copy the configurations and files.

2) Use a CF/USB drive to boot (or create a nanobsd image) whereas the rest of the system resides in HDD with zfs. Thus, migration later would be easier.

Obviously, the nanobsd way has a steep learning curve, but I found it extremely useful for dynamic systems.

*DISCLAIMER: @mfaridi:I have no idea about the affordability and availability in your region. ;-) So pardon me if this does not apply in your case.
 
Thanks guys, I think the FreeBSD label file system is great, and works good for me. I use the Generic kernel and do not modify the kernel. Can I use label with a Generic kernel?
 
There can be entries for CD and DVD in /etc/fstab, but they're just device names like /dev/cd0.

glabel(8) implies that labels for the individual CD media will be created in /dev/iso9660/. I'd expect it to get the label from the volume ID (-V option for mkisofs(8)), but haven't tested it.
 
I have a lot of files and information on my hard disk. Can this approach cause problems for me and may I lose all of my data?
 
Don't worry, you will have no problem, unless you mess with your disk and/or MBR. The only problems you might face, is the device naming in /etc/fstab, as most others have stated, and your graphic card -in case you kldload some specific driver-. The former may result in a non-bootable-easy-to-fix system (even if you don't create labels), the second may result in a non-working Xorg, unless you fix your /etc/X11/xorg.conf file to suit your new needs (or whichever configuration file you use for X)

Good luck and don't worry. I, and I speak of myself, have never kept a backup when I had to do such operations, but that's me and my relationship with backups :). If your information is valuable, you should keep a backup regardless of you moving your disk to a new system.
