I need your advice because I'm not very advanced in creating workflows.
The situation is as follows: in the Lead entity I have an option set with a lead source, the same option set also in the Client entity. When I qualify a lead record to the client record, the value from the 'lead source' field is transferred to the client. So mapping is working. The problem is that both option sets have had different elements and their IDs so far. I managed to unify them, but I need to fix the values in 'lead source' field for existing records in the Client entity.
One way is to export the entire database (30k records) to Excel and change the value in this field, and re-import. However, I thought maybe it could be done faster using workflow.
I want to find client records with existing originating lead and then copy value of the 'lead source' field from this originating lead to the 'lead source' on client. Can anyone guide me?
