To be honest, you should setup Azure Event Hub, sync it with MongoDB Atlas Triggers, and make a function to just migrate/pour the data over into MongoDB. Or make an HTTPS call, or just use the GraphQL functionalities. There’s a dozen options to achieve this exact task essentially, the bigger focus I’d say is just exporting the data into BSON or JSON and sending it over to MongoDB to ingest and it’ll all be there, just make sure you build the schema correctly etc.
EDIT
@Ramesh_k1 Just use JSON as a the target type, and export the data to JSON. Start up compass, login to your MongoDB Cluster, and upload the JSON file.
You have now migrated your data using the simplest process.
