Go ahead. However, the upgrade process traverses the package tree in dependency order AFAIK, so at any point during the update, a qt-old version library was either already overwritten by its qt-new counterpart, or should not be referenced by the linker anyway, unless the ports dependencies do not reflect the linker dependencies, or qmake is messing up the library search paths for it's build/stage-dir libs with the system path's ones.
