-------------------------+-----------------
 While migrating from one machine (running El Capitan) to a new one
 (running High Sierra) I ran into an unexpected issue which I think should
 be mentioned on the Migration page of the wiki
 (https://trac.macports.org/wiki/Migration).

 Because of the difference in the operating system between the two
 machines, I started out by setting up various things on the new machine
 fresh out of the box, including installing MacPorts and several ports.
 After this, I used the Migration Assistant to copy over the data files
 associate with the (only) user on the old machine (via its Time Machine
 backup).  I specifically unchecked the options to copy over `/opt.../` and
 Computer settings.  I was merely trying to copy over the data files
 associated with that user and these were being written to a different
 username than was setup on the new machine.  However, despite this I found
 that my MacPorts installation and several ports were corrupted as a result
 of using the Migration Assistant.  After messing around with trying to
 follow the migration instructions after the fact for a while, I had to
 resort to wiping all ports and MacPorts itself and start from scratch.

 I'm willing to make the necessary edits myself, but since I've never
 actually worked on the wiki before, I thought I'd post this issue in order
 to get feedback on the proposal first.

 As a result of this, I think the wiki should warn people that use of the
 Migration Assistant should be done before installing and using MacPorts on
 a new machine.
