Upgrade without data loss

[Schmill]

I know there are the usual warnings about making sure you have a backup etc, which I do, but...

 

What is the correct process to upgrade from 5.0 4528 to 5.1 5022?

 

I have the img for the USB, and the necessary PAT file, and I know I can install a completely new fresh system, but how do I do it on my live system, and not have the existing data completely wiped during the install?

 

Thanks

Just boot the new image and install.

Does that not erase any attached drives?

Nope.
