At first I was wondering why we had:
T3h D34dly Thrad Necromancy!11!
and feared SPAM, but I see you have a real question. I am not sure I understand the first part, so I will go to the second:
Yes, you can clone with
SuperDuper!. You can boot off the clone and then have it clone to your new drive whilst you do whatever foul unmentionable things you do
Now if I understand correctly, I have never tried doing what I
think you are doing--cloning a
lower OS to an Intel-Macbook. However, I think the
easiest thing to do is the following:
1. Clone your current Tiger to the Ext-HD with
SD.
2. LOAD Snow Leopard on the new drive--format, load, all of that.
3. Have your Ext-HD connected.
4. The Installer should at the end of things ask if you wish to transfer a
current account. You
should be able to do that directly with the
Migration Assistant. That should bring everything over onto Snow Leopard.
Now, you will probably have to update a lot of software to their Snow Leopard levels.
