How to replicate a local mongo database to atlas
To replicate a local MongoDB database to Atlas, you can use the MongoDB Atlas Live Migration feature. Here are the steps to follow:
Create a new MongoDB Atlas cluster or select an existing one where you want to replicate your local database. Make sure that your local MongoDB server version is compatible with the Atlas cluster version. You can check the version compatibility matrix on the MongoDB website. Whitelist the IP address of your local MongoDB server on the Atlas cluster. In the Atlas cluster, go to the "Data Lake & Tools" tab and select "Live Migration". Click the "Create Migration Job" button and provide the required details such as the source database connection string, the destination cluster details, and the migration options. Configure the migration settings such as the data transfer rate, the maximum batch size, and the conflict resolution strategy. Start the migration job and monitor its progress using the Atlas Live Migration dashboard.
Once the migration is complete, you can verify the data in the Atlas cluster and switch your application to use the Atlas database instead of the local one.
