This morning I was trying to migrate an older Window 10 Pro computer to a new Windows 11 Pro computer, one thing I almost always do is to backup the C:Users<Name>appdatalocal and .roaming Mozilla profiles to then copy into the new Mozilla profile on the new computer. No matter what I tried every directory and file copied as a copy and would not overwrite the existing files in the profile directories no matter what I did.

First both Explorer windows were run as Administrator, Google turned up a file explorer option called “Hide folder merge conflicts” which I unchecks but nothing I tried allowed me to overwrite the new profile files with the old profile files. And both versions of Firefox were the exact same version.

How can I overcome this problem?
