    11== Migrating a MacPorts install to a new major OS version or CPU architecture ==
    22
    3 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.
    4 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.
     3A MacPorts installation is designed to work with a particular operating
     4system and a particular hardware architecture. Upgrading the operating
     5system (e.g., from Mavericks to Yosemite) or migrating to a new machine
     6with a different architecture (e.g., from PowerPC to Intel) will
     7generally cause problems. The following procedure is designed to prevent
     8such problems.

     11scenarios listed above also applies.)
