New Google Apps Domain Connected To Existing Zoho CRM

New Google Apps Domain Connected To Existing Zoho CRM

Hello all, 

I have a domain that i want to switch to Google Apps.  My question is, can I integrate it directly to my current Zoho CRM that I have been using for a year, or do I have to create a new Zoho CRM?  If I can integrate to an existing Zoho CRM, are there instructions on how to do that?  If so, where or how?

Thank you, 

Chris
