I dunno about "better" but I use a somewhat different strategy.  It's been
a while but it's very roughly this:

- Install the new drive by some means
- Quiesce all highly active processes like web and db servers
- dd if=/dev/old-drive of=/dev/new-drive
- Shut down and remove old drive
- Reboot from recovery media like a linux repair disk that has 'gparted' on it.
- Use gparted to edit and resize (grow only) the relevant partition(s)
- Reboot and use 'growfs' to make the full disk size available to the filesystem(s)
