Moving my Aperture 3.6 library to Lightroom

Hi All,

I have been using Lightroom CC on my computers (mostly on MacBook Pro at home) since 2020 and love it.  However, I still have loads of old photos on Aperture 3.6 left on my office iMac running Mohave 10.14.6 and I'm worried I'll lose them if I don't also move them to Lightroom soon.  It seems Aperture doesn't even run on newer OS versions!

All the relevant posts I see refer to moving Aperture libraries to Lightroom Classic, not Lightroom as part of Creative Cloud.  Can someone help me with the proper method to move my library to my version of LR?
