Connecting Stand Alone Marketo to New SFDC instance

Hi Jane,

This is a complex situation. In Marketo, your existing leads have been there for a while and have their whole activity log attached to them. You probably do no want to delete them because you care about this activity log, all the capability it gives you to target based on passed behavior.

But Marketo will not deduplicate what is arriving from SFDC. So 2 solutions here:

• Either your SFDC instance is completely empty and you have not started to inject data into it. You can set up the link and push all the leads in Marketo to SFDC. Then you import your data in Salesforce and deduplicate on import
• Or your have already started to import data in Salersforce. Unfortunately, you will not be able to avoid the creation of duplicates in Marketo as Marketo does not dedupes leads/contacts that come from SFDC with anything that is already in the DB. In this case, you will have run run a deduplication process just after your initial sync. You may want to use Marketo's Easy Merge service or this new tool: Re: New Deduplication App for Marketo

Another key point will to avoid existence of duplicate columns as well. You may have created fields in Marketo, that correspond to fields in SFDC. When you will be setting the sync, these 2 fields will NOT be merged. ou will have to remove all usage of the Marketo only fields (from any smart list, smart campaign or form) and then hide them, and then ask Marketo support to remove them from your user interface.

I agree with Greg, and just to reinforce, if this is a truly new SFDC instance, then your best choice is to allow Marketo to be the source of the data. Sync over the new leads from Marketo into SFDC instead of doing a dataload or any other method. This will preserve the connection between Marketo and SFDC records and avoid duplication.

Your Marketo custom fields will be an issue. Marketo support can do a remapping so that you can merge your existing Marketo field with a new Salesforce field without needing to remove all field references, but they will only do this for up to 10 fields for free. Beyond that you will need to contact Marketo professional services and do the remapping for a fee.

Depending on how these fields are in use it may be worth while to go this route, as opposed to removing your fields from every smart campaign and asset that references them (may be in the hundreds) and then moving all your data into the new fields and rebuilding all your smart campaigns and assets.
