Sounds like a pretty good way to destroy the data on your new drive :)

I have migrated drives before (this workstation has migrated 3 times
without a rebuild).  I simply perform a minimal install on the new
drive, then boot in rescue mode, mount comparable file systems from each
drive and cp -pR the contents.  For example, assume new drive is hda,
old is hdc.  / is on hda1 and hdc1.  Do this:
mkdir /mnt/oldroot
mkdir /mnt/newroot
mount -t ext3 /dev/hda1 /mnt/newroot
mount -t ext3 /dev/hdc1 /mnt/oldroot
cd /mnt/newroot
for I in home var bin etc lib mnt root  tmp dev floppy opt sbin usr; do
    cp -pR ../oldroot/$I .
done
mkdir boot proc

*NOTE: I may have missed something as it has been a couple years since I
did this last.

Granted, this blows away your new RPM database, binaries, etc, but it
replaces it with all the old stuff from the old disk.

Make sure you edit /etc/fstab, if necessary. You may have to run lilo.
If so:
chroot /mnt/newroot
lilo
exit
