I would say the situation with 10.15 is now similar to other OSes. Some 
things work, some things do not. There are also some clear cases of 
things not working, and cannot/willnot be fixed, such as 32 bit support.

At the end of the day though only you know which ports you really care 
about, and cannot live without, so you need to do your homework 
yourself. Identified those ports and then check their status at


Finally, as with any major OS update, I strongly recommend making a full 
bootable clone of your current system, before doing anything. Then, if 
worst comes to work, reverting back is trivial. I recommend this for any 
OS update, not at all specific to MacPorts...
