We’re excited to announce the Public Preview of a significant enhancement to the Azure DocumentDB (with MongoDB compatibility) Migration extension for Visual Studio Code—introducing online migration capability! This update makes it easier than ever to migrate MongoDB workloads to Azure DocumentDB with minimal downtime, maximum efficiency, and a fully managed experience.What Is the Azure DocumentDB Migration Extension?The extension is designed to simplify the migration process for MongoDB workloads. It provides a developer-friendly experience within Visual Studio Code, enabling you to assess, plan, and execute migrations without complex setups or additional infrastructure.What’s New in This Update?The migration process is now seamless and disruption-free. With online migration, you can move data directly from your MongoDB instance to Azure DocumentDB without service interruptions. The extension also introduces private endpoint support for secure connectivity and a fully managed experience—Azure handles all migration resources and infrastructure for you. Best of all, there’s zero cost and zero deployment effort required.How It WorksMigration happens in two phases: Initial Bulk Copy moves the majority of your data to the target environment. Change Stream Sync captures real-time changes—such as inserts, updates, and deletes—and applies them to the target database, keeping both environments in sync until cutover.This approach ensures minimal downtime, data consistency, and dynamic efficiency without freezing your workloads.Why Developers Will Love ItEverything happens inside Visual Studio Code through an intuitive interface. You can run a comprehensive workload assessment, choose specific databases and collections for migration, and let the extension automate resource deployment in the cloud. No manual setup, no bandwidth concerns—just a smooth, guided experience.Getting StartedOpen Visual Studio Code, head to the Extensions Manager, search for “DocumentDB”, and install the Azure DocumentDB Migration Extension. Follow the six-step wizard, and you’re ready to migrate.In SummaryThe Azure DocumentDB Migration extension (now in Public Preview) makes migrating MongoDB workloads to Azure Cosmos DB easier than ever. With online migration, selective options, and minimal downtime, you can confidently modernize your database environment.Check out the documentation and FAQ to get started today.About Azure Cosmos DBAzure Cosmos DB is a fully managed and serverless NoSQL and vector database for modern app development, including AI applications.
