Changing site name in SP2010 & keeping links in PWA2010

Hi,

As the title suggests, we want to change the SP2010 site name but keep all the referenced links in Project Server (PWA) 2010.

So that the project sites are linked to the sharepoint docs when the name changes in sharepoint.

How would I change the SP site name and ensure that my MS Project plans keep the link? thanks for your help
