WiIN 11 Set up issues

+Just started a new minicomputer with WIN11.  Moved data from old WIN 10 PC using a transfer cable. Had to use a transfer cable because the initial set up on new PC did not identify it was downloading data from original One Drive back up. Suspect it was working but did not provide any visual status to activity and % complete.  My solution was a transfer cable

Now find I have my old WIN10 desktop complete with all my original programs and documents, together with a new WIN 11 start screen which does not have access to my original programs unless I download them from the original site.

Confused and disappointed in the whole process.

If I now D/L programs from vendors site, do I have 2 copies   -  say original office on WIN10 desktop and a second version downloaded on WIN 11 start menu
