Both Aperture3.6 and iPhoto 9,6.1 are supported on OS X Yosemite and OS X El Capitan, Sierra, High Sierra (some minor issues, and you can no longer order print Products from Aperture) and Mojave. You can continue to use Aperture 3.6 or iPhoto 9.6.1, while you are exploring Photos, so you will know, how to prepare best for the migration. Do the migration before you upgrade to macOS 10.15.
