I always did a clean install on major version changes. This time I thought I'd see what would happen with an upgrade from LM19 to LM20. Went relatively smoothly, and was surprised. Did wipe out all my ppas and additional repos, so adding those back in, had to re-install virtualbox, but overall think less effort than starting again.
Note - manual partitioning during install is off the 'something else' option.
I think you mentioned somewhere that you had the gm10 tools and ppa aboard when you did the in-place upgrade.
Same here, and it also wiped all ppas and every repo including focal and ulyana. To further test I did a fresh install of Mint 19.3 adding no additional sources or ppas, but installed all available 19.3 updates. Also by this time the upgrade instructions had been revised. That in-place upgrade went smoothly--but still time consuming.
