Data Transmission Service (DTS) is a data transfer service that integrates such features as data migration, sync, and subscription, helping you migrate your databases without interrupting your business and build a high-availability database architecture for remote disaster recovery through real-time sync channels. Its data subscription feature grants you real-time access to incrementally updated data in your TencentDB instance, so that you can consume such data based on your business needs. Currently, DTS for MongoDB supports data migration on different versions of MongoDB and in multiple network scenarios.
|Source instance||Source instance to be migrated.|
|Target instance||Target instance to be migrated to, i.e., user-purchased TencentDB for MongoDB.|
|CVM-based self-created database||MongoDB service deployed on a CVM instance.|
|Public network-based self-created database||MongoDB service deployed on the public network.|
DTS supports data migration and data sync in common scenarios, such as public network-based, CVM-based self-created, Direct Connect-based, VPN-based, and CCN-based databases.
Notes on migration
Log in to the DTS Console and click Create Migration Task on the data migration page. Select the corresponding region in Linkage Region, and click Buy at 0 USD.
- Currently, MongoDB data migration is free of charge.
- Please select the region with caution as it cannot be changed once the migration task is created.
On the "Set source and target databases" page, select MongoDB as the source database type, and configure the instance and the corresponding account/password information.
Please create a read-only account in the source instance for the migration; otherwise, the verification before migration will fail.
Test the connectivity between the source and target instances.
On the "Set migration options and select migration objects" page, set the migration options and migration objects (you can select specified tables).
On the task verification page, complete the verification before migration and click Start Task.
