How to avoid duplicates in Mysql to MongoDB data migration?

I am using studio3T for data migration from SQL to MongoDB.
Please help me resolve an issue, i.e., Avoiding Duplicate data while migrating the data.
At first time we need to insert the data but next time if we run migration the already existing data must be updated and new data must be inserted, Something similar to upsert.
I did not find any solution regarding this issue in Studio3T.
Please would anyone help me with this issue.
