Comment (by trac.macports@…):

 Thank you.

 I used the forced deactivation command and right now all remaining
 outdated ports are being upgraded.

 I always wondered, is there a simple command that would delete all older
 versions of installed ports while retaining some of the older ports (and
 their dependencies) that I really wanted to use?
 And also, is there a way to install older versions of ports?

 I know this is not a Q&A platform, but could you enlighten me since the
 docs are so complex and you are already talking to me?

 :)
 Thanks again,
 Thomas
