When migrating an on-premises MongoDB database to Azure Cosmos DB, which tool should be recommended for the migration process?

1. Data Migration Assistant

2. Azure Storage Explorer

3. Aruz Cosmos DB Data Migration Tool

4. mongorestore

The correct answer is: mongorestore

The best choice for migrating an on-premises MongoDB database to Azure Cosmos DB is the Aruz Cosmos DB Data Migration Tool. This tool is specifically designed to assist with the migration of data to Azure Cosmos DB, making it well-suited for this purpose. It can handle various data formats and provides a seamless transition by addressing the specific requirements and optimizations necessary for Azure Cosmos DB. Using this tool, you can easily configure the source MongoDB database and specify the target Azure Cosmos DB account. It assists in transferring your data while facilitating the management of database structures and settings, ensuring that the data is not only migrated but also optimized for performance within the Azure environment. While the other options may have functionalities relevant to data management, they do not provide the specific capabilities tailored for migrating from MongoDB to Azure Cosmos DB. For example, the Data Migration Assistant is typically used for SQL Server migrations, and Azure Storage Explorer is more focused on storage management rather than database migration. Meanwhile, mongorestore is a tool primarily for restoring MongoDB databases from backups, making it less suitable for migrating data directly into Azure Cosmos DB.
