1. Install the new 60GB drive in the machine alongside the existing drive.

2. Download Carbon Copy Cloner (or SuperDuper!, whichever you prefer -- I like CCC).

3. Use CCC to "clone" the 6GB boot partition to the new drive (or new partition on the new drive).

4. Set the Startup Disk preference pane to boot from the newly installed, newly cloned hard drive.

5. Verify that the server operates normally while booted from the new drive.

6. Remove the old drive (or simply disconnect it) and boot from the new drive again, once again verifying that everything works correctly and that mountpoints and shares and what-not are operating as expected.

If you chose to give the new drive a different name than the old drive, you may want to check shares and mountpoints to verify that they are mounting and sharing correctly from the new drive.
