BuildForge 7.1.3 and CQ 7.1.2 Reqpro 7.1.2.3

Hi,

I have BuildForge 7.1.3, CQ 7.1.2 and ReqPro 7.1.2 installed in one box. Now I am planing to upgrade CQ to 8.0.1 version.

CQ Installed in c:\IBM\RationalSDLC
ReqPro installed in c:\IBM\RationalSDLC ( same in CQ )
BuildForge installed in c:\IBM\BuildForge

What if I upgrade CQ to 8.0.1? Does it allow me to upgrade only CQ? Does ReqPro or BuildForge will stop proceeding upgrade?

Any help much appreciate on it.

Thanks
