You had a typo there.
I am not sure why you need to empty your wallet and clone your hdd.
You can just install the new version and everything should work just like it did before.
Dude I always fear loss of info.
So I did a screenshot of my choices and I simply can not recall what option to pick
keep both bitcoin cores or replace 16.0.1 with 16.0.3
I don't see any reasonable reasons to keep older version, just replace it with newest version. Even if you're paranoid, verify the validity of the installation and backup wallet.dat should be sufficient.
Also, there's no report that wallet.dat, blockchain or chainstate corrupted/missing after upgrade 0.16.3
thanks I will do replace option.
and it worked fine .
