Upgrade Netweaver Portal excluding HR buisness package

Hi

We are in a process of upgrading our portal from Netweaver 7 to Netweaver 7.4.  We want to exclude HR buisness package while upgrading.  Kindly let us know whether there is an impact on excluding the HR buisness package while upgrading to NW7.4. I have attached the screenshot of existing  version of buisness package.

Regards
