Hi Shawn
I recently clean installed v. 1803 on my new SSD, which replaced the old HDD.
Before starting I took both a Full Macrium image and a separate backup of the Edge Favorites, following my preferred method Option 2. Just for extra precaution, I was wise enough to also export an html file, using Option 1.
As I had other priorities...like re-installing all my apps
I didn't restore Edge favorites on time, before I was offered to install 1809.
So I did Update to 1809 and when I tried to restore the favorites using Option 3, from the v. 1803 backup I had ...Edge got lost altogether!!!
Couldn't open the app or do anything of course with the favorites. So I went to the Settings and "Reset" Edge and I was lucky enough to get it back!
But both the separate favorites backup I had and the files in the Macrium image were unusable with the new version i.e. 1809.
Luckily for me as I said before I was cautious enough to also get an html export, which of course loaded to Edge and I got everything back to normal.
So I would like to suggest, that you make a note in the tutorial, that Options 2 and 3 work only if Edge backups are going to be restored in the same Build of Windows or at least the same version of Edge, cause nobody knows what changes each update brings. Moreover if someone wants to use Options 2 and 3, to be in the safe side, he should always have a recent copy of an html export (my preferred method from now on...like it is yours! ).
Cheers mate!
