Hmmm...
Wonder if anyone can help, I too have an external USB enclosure for my MBP and am looking to migrate to Snow Leopard (from Leopard) and upgrade hard drive at the same time.
However I don't wish to use the Time Machine method as I want a clean install (I come from a PC background and still think spring cleans are a good thing, I removed Parallels a few months ago and notice there is still the odd mention of it in places for instance).
I would also like to get everything working before butchering my MBP and changing the internal hard drive.
So I have connected the new HD via the the external USB and booted from the SL DVD installing a fresh copy and all has worked fine. I can boot from SL on the external USB whilst still having my original HD visable within the machine.
BUT when I run Migration Assistant and click "Continue" SL requests my admin password, which I enter then I end up back at the same click-to-continue screen. It appears that the Migration Assistant does not like something. I was hoping to install all my Apps by hand but wanted to migrate emails, key chain etc - does anyone have any suggestions?
Many thanks in anticipation.
