Migration Service
Tencent Cloud Data Transmission Service DTS is an integrated database data transmission service that provides data migration, synchronization, and subscription. It enables users to easily migrate their databases to the cloud without interrupting business operations. DTS for MongoDB supports one-time migration to cloud databases, allowing for both full and incremental data migration, meaning that it transfers both historical data from the source database and any new data written to the source database during the migration process.
Migration Overview
Content Overview | Note |
Introduces the features currently supported by DTS for MongoDB and the applicable use cases. | |
Describes important considerations and related limitations during the use of DTS for MongoDB. | |
Describes the specific operations for using DTS to perform migrations. | |
Before a DTS migration task is started, performing necessary pre-checks is crucial to prevent and resolve potential issues such as database connection problems or table conflicts. This document introduces common issues encountered during the pre-check process. |
