How can I map values from one field to another?

[Anonymous]

We have our Marketo and Salesforce instances synced, but I realized after we launched our Lead Scoring program that we hadn't created the Lead Score field in Salesforce first, so all of the data is stored under the Lead Score field in Marketo. How can I sync the Marketo Lead Score field values to the corresponding Salesforce Lead Score (L) field for each lead?

My initial thought was to run a "Change Data Value" batch campaign for the Lead Score attribute, but it requires you to enter a numerical value rather than a different field.

You can use tokens in change data value flows. So instead of giving a number, you can put {{lead.Lead Score}} or whatever the field is you want to copy.
