I have 2014 Mac Mini with fusion drive running Catalina. If I replace original fusion SSD with bigger one, can I restore Time Machine backup or reinstall OS?

  • why would you suspect that you couldn't...

    If you're going to replace the original SSD with a new SSD of sufficient capacity, then don't make it a Fusion drive: just use it as an SSD. Fusion drives are a compromise between speed and space: if you're increasing the SSD space, you don't need to cripple the speed by fusing it to an Hdd.
