Integrate Opportunity AX 2012 to CRM 2011 using connector?

Hi, I want to know if we can create a custom mapping and integrate Opportunity from AX 2012 to CRM 2011. We need to puch Opportunities from AX 2012 to CRM 2011 online. Is this doable? If so, could someone point me in right direction? 

Also could we be able to push leads and Quotes from AX to 2012? 

Thank you;
