Is it possible to change the Google Apps domain for ZohoCRM environment?

Hello

We started to use ZohoCRM by adding ZohoCRM as an application from  https://www.google.com/enterprise/marketplace/viewListing?productListingId=2533+17854168373705313802&pli=1 for one Google Apps domain let say www.google.com/a/domain1.com. Now we would like to change the Google Apps domain bounded with this ZohoCRM environment to another domain let say www.google.com/a/domain2.com.  I've found only disable/enable switch in Setup/Apps & Add-ons/Zoho CRM for Google Apps setting page. 

Is it possible to change the Google Apps domain bound to the specific ZohoCRM Environment?

Is another way to do it e.g. must we create new ZohoCRM environment from domain2, copy all customizations and export / import all data?
