title: MacPorts migrate is not working with Catalina
body: <p>I just updated my computer from High Sierra to Catalina and MacPorts give error. </p>
  
  <pre><code>Error: Current platform "darwin 19" does not match expected platform "darwin 17"
  Error: If you upgraded your OS, please follow the migration instructions: https://trac.macports.org/wiki/Migration
  Error: /opt/local/bin/port: Failed to initialize MacPorts, OS platform mismatch
  </code></pre>
  
  <p>However when I try to migrate it command like these <code>sudo port -qv installed &gt; myports.txt</code> are not working also. </p>
  
  <p>I had some version specific packages to run my project. Also I could not find the support for Catalina in their website. What do I need to do?</p>
