For a few months our SFDC administrator had flipped off the Pardot/SFDC to triage some issues, and during that time, some SFDC records were created that do not exist on Pardot, so we are unable to get scores and grades for these leads.
I've just collected all leads in Salesforce that need to be created in Pardot. I would like to use the LeadID to upload the record to Pardot with minimal field mapping. However, I believe all currently mapped custom fields in Pardot are set to sync the records according to the most recent data.
If I create these records, only mapping the lead ID on the Pardot Prospect Import, will it wipe out all of the data in SFDC? Thanks in advance for the help!

Hello,
I think the approach you are proposing here, whereby you are matching Prospects to their Lead or Contact ID is the right one.
In terms of the data potentially being lost this is something I'd suggest proceeding with carefully.
I've not had experience of this scenerio before however I'd suggest trying this out with one prospect first being updating the rest.
This way you can check if the next sync causes issues with data being updated etc.
Prior to this I'd suggest taking a full backup of the Salesforce Record just in case.
I know from the Pardot Connector itself you can actually set what field wins when there is a sync conflict so for those syncing to Salesforce is suggest checking this also.
Thanks Tom
