correct way to migrate old data on hda to new sda

[geisj at pagestation.com (Jerry Geis)]

I am migrating off of a 40GIG hda to a new 160GIG sda disk.

I plan on installing 4.2 from scratch. But after that what is the 
correct way
do transfer all the data from hda (home partition really) to the new sda 
home
partition?

I presume there is just a couple files in /etc to restore also. Like 
hosts, passwd.
Anything else?

Other suggestions welcome also. this is my first time migrating to a new 
disk.

THanks,
