“As part of our modernization initiative, we successfully harmonized workloads and converted seamlessly our MongoDB databases to Oracle Autonomous Database as well, achieving significantly better performance and operational efficiency. The results have been very impressive!”

Arman Ashouriha Head of Oracle Cloud Infrastructure Modernisation Programme

MongoDB to Oracle Database migrations made simple

Save up to 50%

Oracle offers lower prices. Eliminate the need to overprovision by dynamically scaling.

No new contracts

It’s easy to get started. Use your existing contracts and credits from Oracle, Azure, Google, and AWS.

Migrate into any cloud

Move from MongoDB or MongoDB Atlas to any Oracle Database—on premises or in any cloud.

Maintain business uptime

Applications can stay online during migrations.

100% JSON, no changes required

MongoDB collections transfer as is to Oracle Database JSON collections without any changes.

Plan for your entire estate

Visualize your entire MongoDB estate, understand the migration effort needed, and project future cost savings.

Oracle migration planning tools help you make informed strategic and tactical decisions by providing recommendations that consider the size and deployment patterns of your MongoDB estate, database usage, and resource consumption.

  • Receive evaluation of migration compatibility
  • Act on prioritized migration recommendations

Your migration workflow begins with a choice of MongoDB extracts using MongoDB or Oracle tools. Premigration diagnostics evaluate JSON compatibility with the target database and highlight exceptional MongoDB application usage. Choose offline or online data migrations with GoldenGate for MongoDB Migrations. After the data movement completes, application connectivity and performance are validated prior to the final switch over.

Migration workflows diagram, description below:

Your migration workflow begins with JSON sources, which can be MongoDB, MongoDB Atlas, or flat files.

Using the MongoDB to Oracle Migration Tool, deployed as a VS Code in SQL Developer, users register source and target databases and select between online or offline migration. The Oracle MongoDB Compatibility Advisor assesses source and target compatibility, looks for problematic content, and makes corrective recommendations.

After errors are resolved, the flow continues to either offline or online data movement. For offline processing, mongodump or mongoexport output or JSON clear text files are read directly by the Oracle Database API for MongoDB and written into the target database. Oracle GoldenGate can also be used to read directly from a MongoDB and written to an Oracle Database target. Note for online migrations, GoldenGate is the only choice. After an initial data load of older data, new data is captured in real time and replicated to the target database.

The validation step follows the migration execution where customers use their own application testing tools to validate operations and performance. Oracle Databases have tuning and diagnostic tools to validate performance. Oracle GoldenGate Veridata is an optional tool that compares MongoDB JSON data sources against target Oracle Databases JSON data in real time while applications are offline or online for guaranteed data synchronization. Note that GoldenGate Veridata is a separately licensed software product.

Once applications and data are validated, applications switch over to the new Oracle target database.


See GoldenGate for MongoDB Migrations videos, documentation, and Quick Start for step-by-step online and offline data migrations.

Oracle migration tools support all self-managed and managed MongoDB sources across cloud platforms, including MongoDB community and enterprise editions.

Sources diagram, description below:

Oracle migration tools support all self-managed and managed MongoDB sources across cloud platforms, including MongoDB community and enterprise editions.

MongoDB Atlas is a managed service and supported by AWS, Azure, Google Cloud, and a variety of other cloud providers. Amazon DocumentDB and Azure Cosmos DB are variants of standard MongoDB and migration from those versions are also supported.

Customers’ self-managed MongoDB versions running on-premises or in Oracle Cloud Infrastructure (OCI) are supported.

You can migrate to any of the Oracle Database platforms below, all of which support JSON document processing. Migrations can run with zero downtime while apps remain online and can run securely across separate firewalls.

Oracle Database targets diagram, description below:

You can conduct database migrations, either offline or online, with zero downtime with the following OCI, on-premises, and multicloud target Oracle Database offerings.

OCI targets include customer-managed Oracle Databases, Base Database Service, Exadata Database Service, Autonomous Database, Autonomous Database on Exadata Cloud@Customer, Exadata Cloud@Customer, and Autonomous JSON Database.

On-premises migration targets include Oracle Database Appliance, Exadata, and customer-managed Oracle Databases.

Multicloud targets include Oracle Database@Hyperscale running on OCI, deployed in Google Cloud and Azure for Autonomous Database and Autonomous JSON Database, and Exadata Cloud Service. On AWS, only Exadata Cloud Service is currently supported.

Business continuity migration methods Network connections

Offline migration

  • Applications are offline during migration
  • Entire database is duplicated in one operation

Direct connection

  • Source and target are on the same physical or virtual network

Online migration with zero downtime

  • Applications are online during migration
  • Incremental changes to the source database are captured in real time and continuously applied to the target database

Indirect connection

  • Source and target are on separate networks, likely behind firewalls
  • Access across networks requires a secure agent

MongoDB to Oracle migration testimonials

  • SaaS Migration – when scale gets real

    Boon Software launched their Symphony Mobility solutions suite using MongoDB. As their suite expanded and their processing demands grew they soon hit the wall for performance and easy manageability. That’s when they made the switch to both OCI and Autonomous JSON Database migrating with the Oracle Database API for MongoDB. Now they have expanded their application substantially and improved customer satisfaction.

  • Embracing simplicity over complexity

    "We successfully migrated from MongoDB to Oracle Autonomous Database with minimal effort. The process was efficient, using standard export/import tools, and required only minor adjustments to our applications. The transition was smooth, and we’re satisfied with the stability and performance we’ve experienced since."
