As long as your ports tree is not very old, you will be able to use it
in newer system but this is not always guaranteed.  It is, however,
possible to checkout ports tree from the date you specified with either
cvsup or cvs.

My personal suggestion is that when upgrading, try to build a new
environment from scratch (say, everything is brand new) with ports named
by 'pkg_info -qoa' on old system, and have the new environment reveal
potential issues before making major updates to running system.  Another
possible approach is to update from time to time but this could cause
you a lot of downtime.
