I have the 2019 Audiophile version of BiaB on an external SSD. I have just ordered the 2020 upgrade. Do I just unplug the old SSD, plug in the new one and hit the exe file, or is there something else I need to do?

Secondly, I am in Australia and I have had three 'UPS Exception Notification' messages on this order - all for different reasons. So the new SSD might not even get here. If I have to download the new files where do I install them? Do they go on to the existing 2019 external SSD?

As we have some of the world's slowest internet speeds here I hope the SSD arrives safely. Last time I had to download 500Gb of files for a PC re-build it took two weeks of continuously downloading day and night. Snail mail is actually faster than the internet here.
