Yes Happy Ever After is a good place to start. I did my first one a couple of weeks ago. This is the hard part. I like FSD and there is a new install ISO out that wooks good. Here is a link to a tutorial on copying game saves to a new profile that I did and a link within to upgrading your internal drive.

You can use an FTP client to copy files to your hard drive using xexmenu that is very useful.
It will take you a while to figure it all out.
Also learning how to configure lauch.ini (dashlaunch) is key so you can sart xemenu, FSD or NXE by pushing button on controller.
Here is the contents of mine if it helps
