So if I `sudo cp -R /opt/local/macports` to a suitable location & use
the ports installed file (I regularly take a snapshot of ports installed
via `port -qv installed > myports.txt`) that should give me a head start
in case alarm bells start to toll?

I'll also study the migration page although Snow Leopard is where I get
off the train as far as OS X is concerned.
