I am moving over about 10K contacts from our old CRM system into SFDC and attaching them to there current account in SFDC. Since Marketo has been used for the last two years before we moved to SFDC I know most of these contacts exist as leads in Marketo. What I don't want to do is sync them to SFDC as leads then manually have to convert 10K contacts to there correct accounts in SFDC.
So what I am trying/hoping is that if I create them as contacts in SFDC let them sync to Marketo, Marketo then could merge the two records. So far I haven't got a strait answer if this can be done. Seems simple enough match on email - update SFDC ID's. So far no one from Marketo has been able to give me an answers so I figure I would ask the community if anyone has done this. I would imagine I am not the first person to have this issue.
