Share Point in Dynamics CRM

Hi,

I have recently copied our Dynamics CRM Prod to Test instance. We are using Dynamics CRM SharePoint.

After the copy is done, I opened TEST CRM , in the Account entity after I navigate to documents - those document paths are pointing to PROD SharePoint.

I am not sure how do I change the document Path to point to Test SharePoint. Any help or guidance is highly appreciated

Thanks!
