Transferring a FreeBSD on new hard drive [Manual]

Follow this steps to transfer FreeBSD on new hard drive of any size.

• Connect the new hard disk in the system with a FreeBSD (/dev/ad1s1)
• Split the new drive into sections like old one using /stand/sysinstall. Size /dev/ad1s1a may be greater than /dev/ad0s1a.

• Create a temporary folder and subfolders:

  mkdir /backup
  mkdir /backup/root
  mkdir /backup/usr
  mkdir /backup/var
  mkdir /backup/tmp

• Boot up with single user
• Mount partitions:

  mount /dev/ad1s1a/backup/root
  mount /dev/ad1s1e/backup/var
  mount /dev/ad1s1f/backup/usr
  (here specify your own)

• Transfer system:

  ( dump -0f - / ) | ( cd /backup/root ; restore -rf - )
  ( dump -0f - /var ) | ( cd /backup/var ; restore -rf - )
  ( dump -0f - /usr ) | ( cd /backup/usr ; restore -rf - )

• Unmount

   umount /backup/root
  umount /backup/var
  umount /backup/usr

• Turn on Soft Updates

  tunefs -n enable /dev/ad1s1a
  tunefs -n enable /dev/ad1s1e
  tunefs -n enable /dev/ad1s1f

Now you can remove from old hard drive and replace it with new one.
