Doing a NON Clean Install of High Sierra ?

[Jedi]

Hi Guy`s ,

I have my 2 Mac`s a Mini and MBPr and right now they are carbon copies of each other for the most part ( 99.9 % ).

I would like to ask a couple of questions.

1 after using Time Machine 2 back-up both Mac`s , is over installing good or bad ( install as an update ).
Back in the old days starting out fresh was the only way to go.

My Mini was bought new last Nov. with Sierra installed and my MBPr , I had to do a clean install because of issues I was having.

2 However if I install on top of , will the Safari bookmarks and Keychain data remain intact ?

Many thanks for your help ,

Later ,
