In my implementation I have lost sync between CRM and Books.  Books is where all of our day to day work is done.  However I am looking to begin leveraging CRM.

I want to be sure that when I initiate sync, that where a customer company is present in both, that the more recently updated Books data would overwrite the CRM company and contacts data.  When the two were setup I had sync'd the data between the two.  Now we have many new customer organizations and the contact names and titles have been updated in Books.

Is this possible?  When I look at the documentation, it seems that the assumption is made that CRM always has superior data.

Thanks for any clarification you can provide!
