If/when you do update the OS, you should of course follow the 
instructions at

https://trac.macports.org/wiki/Migration

to migrate MP.

Another option would be to restore the MP prefix (/opt/local normally) 
from a backup. Assuming you have backups of course... If not adding this 
to your regular maintenance to do list should be the first thing you do.

OT, but whether or not the mac OS10.13 is smooth or not depends a bit on 
what you update. If we put aside the APFS update for the moment, I 
expect it to be rather painless... I actually have tested the beta in a 
VM and it worked fine, I was able to build all the ports I normally 
install without issue..

The APFS update, for SSD macs, is another thing. This might well cause a 
number of issues. For instance last I heard Xquartz (xorg-server in MP) 
does not work with APFS. No idea if this is fixed (I understand it was 
an Apple issue). I rely on this so I will be holding off the update, or 
at least allowing the APFS conversion, until I hear news on this.. I 
suspect there will be other ports that will need updating to work with 
the new filesystem...
