What are the data migration and synchronization solutions - ApsaraDB for MongoDB

This topic provides an overview of the solutions to migrate and synchronize data to or from an ApsaraDB for MongoDB database in different scenarios.

Impacts

If the minor version of an instance expires or is not included in the maintenance list, ApsaraDB for MongoDB automatically updates the minor version of the instance to the latest version when you perform the following operations. This ensures the performance and stability of the instance.

Limits

Standalone instances do not support incremental data migration and synchronization.

Data migration solutions

You can use the following methods to migrate the data of an ApsaraDB for MongoDB database:
Important
Standalone instances do not support incremental data migration.
- Use Data Transmission Service (DTS) to fully or incrementally migrate the data of an ApsaraDB for MongoDB database. This can achieve smooth data migration from an ApsaraDB for MongoDB database to the cloud without affecting businesses. For more information about DTS, see What is DTS?
  Important
  DTS cannot be used to migrate data from instances that run MongoDB 7.0. For the support of DTS for databases, DTS-related documents shall prevail. For more information, see Supported databases.
- Use the official MongoDB tools of mongodump and mongorestore to fully migrate data of an ApsaraDB for MongoDB database.
- Use a physical or logical backup file to migrate data of an ApsaraDB for MongoDB database to an on-premises database.

The following table describes data migration methods in different scenarios.

Scenario	Source instance architecture	References
Migrate data from a self-managed MongoDB database to an ApsaraDB for MongoDB instance	Standalone or replica set instance	Migrate an ECS-hosted self-managed MongoDB database that uses the standalone or replica set architecture to ApsaraDB for MongoDB
	Sharded cluster instance	Migrate an ECS-hosted self-managed MongoDB database that uses the sharded cluster architecture to ApsaraDB for MongoDB
	Standalone instance	Migrate a self-managed MongoDB database that uses the standalone architecture to ApsaraDB for MongoDB by using DTS Migrate a self-managed MongoDB database to an ApsaraDB for MongoDB standalone instance by using mongodump and mongorestore
	Replica set instance	Migrate a self-managed MongoDB database that uses the replica set architecture to ApsaraDB for MongoDB by using DTS Migrate a self-managed MongoDB database to an ApsaraDB for MongoDB replica set instance by using mongodump and mongorestore
	Sharded cluster instance	Migrate a self-managed MongoDB database that uses the sharded cluster architecture to ApsaraDB for MongoDB by using DTS Migrate a self-managed MongoDB database to an ApsaraDB for MongoDB sharded cluster instance by mongodump and mongorestore
Migrate data from a MongoDB database hosted on a third-party cloud to an ApsaraDB for MongoDB instance	Replica set or sharded cluster instance	Migrate a MongoDB Atlas database to ApsaraDB for MongoDB by using mongodump and mongorestore Migrate a MongoDB Atlas database to ApsaraDB for MongoDB by using DTS Migrate an Amazon DynamoDB database to ApsaraDB for MongoDB by using NimoShake
Migrate data between ApsaraDB for MongoDB instances	Replica set instance	Migrate data from an ApsaraDB for MongoDB replica set instance to an ApsaraDB for MongoDB sharded cluster instance
	Standalone instance	Migrate data from an ApsaraDB for MongoDB standalone instance to an ApsaraDB for MongoDB replica set or sharded cluster instance
	Standalone or replica set instance	Migrate data between ApsaraDB for MongoDB instances of different Alibaba Cloud accounts
	Standalone, replica set, or sharded cluster instance	Migrate data between ApsaraDB for MongoDB instances across regions
Migrate data from an ApsaraDB for MongoDB instance to a self-managed or on-premises MongoDB database	Replica set instance	Restore data of an ApsaraDB for MongoDB instance to a self-managed MongoDB database by using logical backup Restore data of an ApsaraDB for MongoDB instance to a self-managed MongoDB database by using physical backup

Data synchronization solutions

You can use the following methods to synchronize the data of an ApsaraDB for MongoDB database:
Important
Standalone instances do not support data synchronization.
- Use DTS to synchronize data between ApsaraDB for MongoDB instances.
  Important
  You cannot use DTS to synchronize data between instances that run MongoDB 7.0. For the support of DTS for databases, DTS-related documents shall prevail. For more information, see Supported databases.
- You can use the MongoShake tool developed by Alibaba Cloud to synchronize data between ApsaraDB for MongoDB instances.

The following table describes data synchronization methods in different scenarios.

Synchronization scenario	Synchronization tool	References
Synchronize data between instances	DTS	Synchronize data from an ApsaraDB for MongoDB instance (replica set architecture) to another ApsaraDB for MongoDB instance (replica set architecture or sharded cluster architecture) Configure two-way data synchronization between ApsaraDB for MongoDB sharded cluster instances
Synchronize data to an existing instance	MongoShake	Use MongoShake to perform one-way synchronization between ApsaraDB for MongoDB instances
