Multiple Marketo Instances to one instance of SFDC

[Anonymous]

Is it possible to integrate two or more instances of Marketo with one instance of Salesforce.com?

No, there is a 1-1 forever relationship between Marketo and the SFDC Org.

Did your firm merge with another Marketo user? Usually you have to choose the merge process and either choose a Marketo to use going fwd or create new Marketo and new SFDC.

Most firms pick a Marketo and work to migrate the two SFDCs into one SFDC.

Hi Dennis,

Yes, it is possible, but it is exceedingly difficult to do with success.  A Marketo instance can only sync to a single SFDC instance, but the reverse is not strictly true.  I do not recommend this option without exceptional amounts of preparation.  If you are sincerely interested in this option, I highly recommend reaching out to our services team.
