What do you consider an "upgradation"?
means a system that modifies and adds the functionalities in the already installed version QT 4.5 according to the latest version QT 4.7.1
It doesn't work that way. You really have to upgrade to version 4.7 (that is replace 4.5 with 4.7 in your system) and not download a bunch of files and think your 4.5 will suddenly have the capabilities of 4.7.
thanks for clarifying my concepts
