ApsaraDB for MongoDB:Data Transmission Solutions

Automatic minor version upgrades

Limitations

Standalone instances do not support incremental data migration or synchronization.

Data migration solutions

• Available migration methods:

  Important

  Standalone instances do not support incremental data migration.

  • Data Transmission Service (DTS) supports full and incremental migration without service interruptions. What is Data Transmission Service?.

    Important

    DTS does not support migration for MongoDB 7.0 instances. Check Supported databases for compatibility.

  • Use mongodump and mongorestore for full data migration.

  • Migrate cloud data to a self-managed database using physical or logical backup files.

• Migration methods by scenario:

  Migration scenarios	Source database architecture	Documentation
  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 using DTS Migrate a self-managed MongoDB database to an ApsaraDB for MongoDB standalone instance using mongodump and mongorestore
  	Replica set instance	Migrate a self-managed MongoDB database that uses the replica set architecture to ApsaraDB for MongoDB using DTS Migrate a self-managed MongoDB database to an ApsaraDB for MongoDB replica set instance using mongodump and mongorestore
  	Sharded cluster instance	Migrate a self-managed MongoDB database that uses the sharded cluster architecture to ApsaraDB for MongoDB using DTS Migrate a self-managed MongoDB database to an ApsaraDB for MongoDB sharded cluster instance using 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 using mongodump and mongorestore Migrate a MongoDB Atlas database to ApsaraDB for MongoDB using DTS Migrate Amazon DynamoDB to Alibaba Cloud using NimoShake
  Migrate data between ApsaraDB for MongoDB instances	Replica set instance	Migrate data from an ApsaraDB for MongoDB replica set instance to a sharded cluster instance
  	Standalone instance	Migrate data from an ApsaraDB for MongoDB standalone instance to a 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 MongoDB database	Replica set instance	Restore data from a cloud disk backup Restore data from a local disk backup

Data synchronization solutions

• Available synchronization methods:

  Important

  Standalone instances do not support data synchronization.

  • Use DTS to synchronize data between MongoDB databases.

    Important

    DTS does not support synchronization for MongoDB 7.0 instances. Check Supported databases for compatibility.

  • MongoShake, an Alibaba Cloud tool, synchronizes data between MongoDB databases.

• Synchronization methods by scenario:

  Synchronization scenario	Synchronization tool	Documentation
  Instance synchronization	DTS	Synchronize data from an ApsaraDB for MongoDB replica set instance to an ApsaraDB for MongoDB replica set or sharded cluster instance Configure two-way synchronization between ApsaraDB for MongoDB sharded cluster instances
  Synchronize to an existing instance	MongoShake	Use MongoShake to implement one-way synchronization between MongoDB replica set instances
