For me:
1) Shutdown and install the drive
2) Boot LiveCD (I use Ubuntu because "partition manager" is included)
3) Partition new drive with "partition manager"
4) mkdir /mnt/a /mnt/b
5) mount /dev/sdXx /mnt/a (Old)
6) mount /dev/sdYy /mnt/b (New)
7) (a) cp -a /mnt/a/. /mnt/b/. OR
(b) rsync -avz /mnt/a/. /mnt/b/.
8) umount /mnt/a /mnt/b
9) Repeat steps 5-8 for each partition to copy over
10) rmdir /mnt/a /mnt/b
11) Relabel each new partitions (Label or UUID), update fstab & grub (if
included)
12) execute: grub
(a) find /grub/stage1 <-- locate the boot (grub) partitions of
all drives seen by the Bios
(b) root (hdX,Y) <-- set the root to the new drive's boot partition
(c) setup (hdX,Y) <-- sets up the new drives's MBR with root
(boot) partition information
(d) quit
13) Remove LiveCD & shutdown or reboot
14) Set remove the old drive OR set the BIOS to default to
the new drive OR add new drive information to old drive grub
Note:
The above assumes that new drive has enough space
for the data copied over from the old drive partitions as
step 7 copies only the data and not the entire partition image.
FWIW,
Dan
