Okay to clone drive to larger size drive?

[Ohmster]

I have a redhat 9 system with a 27Gb hard drive and am quite pleased with
it. I was running out of room in the /home directories and with a little
help from here, I was able to graft a second hard drive onto the root
tree and mount it a /home. This worked out perfectly, I was able to copy
everything from the old /home directory to the new hard drive, gave it a
label of "home", and you would never know the difference.

Now my root drive is getting full, I run an ftp server in /var/ftp/ and
want more space. Here is what I have:

[ohmster@ohmster ohmster]$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/hda2 27G 22G 4.2G 84% /
/dev/hda1 99M 15M 80M 15% /boot
/dev/hdb1 28G 18G 8.8G 67% /home
none 756M 1.4M 755M 1% /dev/shm
//missy/ohmster_music
74G 43G 31G 59% /mnt/ohmster_music
//cindy/cindy_music 26G 17G 9.3G 64% /mnt/cindy_music
[ohmster@ohmster ohmster]$

Can I use a drive image tool like True Image or Migrate Easy to copy the
original root drive to a larger, 80Gb drive, then swap them out and
reboot? Will this work? Are there linux tools that would work better for
this? fdisk shows the partitions:

Device Boot Start End Blocks Id System
/dev/hda1 * 1 13 104391 83 Linux
/dev/hda2 14 3576 28619797+ 83 Linux
/dev/hda3 3577 3739 1309297+ 82 Linux swap

I want thre swap and boot partitions to remain the same and to have the
root / partition expand to the full size of the new 80Gb hard drive.

How can this be done painlessly in order to get a larger root hard drive
without toasting the system? Please help, I need more room. Thanks.
