+== Migrating a MacPorts install: new OS, Xcode or CPU architecture ==
 
 An installation of MacPorts and the ports installed by it are only designed to work on a single OS release and a single CPU architecture. If you upgrade to a new OS version (e.g. from Leopard to Snow Leopard) or migrate to a new machine with a different type of CPU (e.g. PowerPC to Intel), you may get lucky and have your ports keep working, but in general, things will break.
-If you are only upgrading XCode (e.g. 4.1 to 4.2 on Lion) but not the major OS version or CPU architecture, you do not need to reinstall ports as described below.
+If you are upgrading XCode 4.3, you also need to run `xcodeselect -switch /Applications/Xcode.app` and launch Xcode once to accept its license.
