Review Comment:
   I'm not sure exactly what to say, but "finally" here doesn't quite fit when 
the previous sentences did not appear to be a step-by-step thing (as in "First, 
.... Then, .... Finally, ...."
   
   I think instead of "Finally,", it could say "Upon successfully starting the 
upgrade, it will create" (or similar)
