Generally packages built on an older version of the OS will run on a newer version. When one upgrades to 7x there will be a compat6x port to supply the missing libraries. It's normally not essential to upgrade ports after an OS upgrade, but it is advisable on a major upgrade. Problems are more likely to occur the other way around, there are currently 6-stable packages the wont run on 6.2 because new libraries have been ported into 6-stable.
