How to avoid duplicate records from SFDC to Marketo during data migration.
Hi
Our marketo instance is integrated with SFDC (call it as 'SF1') . We are migrating data from a different salesforce instance (Call it as 'SF2') to SF1. We are de-dupling data in SF1 and SF2. However there can be some common accounts and Contacts which have same email id, data in both SF1 and SF2. So will this create duplicate data in our marketo instance as it's been integrated with SF1 salesforce instance? If yes how to avoid it. If it's not possible, can we separate both the records in marketo instance so that we can easily identify from which salesforce org the data is from?
Please suggest.
