Scenario Overview

Data migration is a one-time task of replicating data from the source database to the target database at the database level. After the migration is completed, the business will be cut over to the new database.
DTS supports data migration from self-built databases, TencentDB databases, and third-party cloud databases.
Scenario
Description
Migration from a self-built database to the cloud
Migrating a self-built database in the local IDC or on CVM to a TencentDB database.
Migrating from third-party cloud vendors to Tencent Cloud.
Such as migration from an Alibaba Cloud or AWS database to TencentDB.
Migration between TencentDB instances
Database version upgrade, cross-region migration (including migration between regions inside China or outside China, or cross-border migration), and the migration between database instances under different Tencent Cloud accounts.

Feature Description

DTS supports access methods such as public network/self-built on CVM/DC/VPN access/CDB/CCN/VPC, with different deployment modes of databases offering various access options. Each access method requires specific network conditions. Please see Preparations.
Self-built IDC databases/other cloud vendor databases: Access methods can include public network/DC/VPN access/CCN.
Self-built databases on CVM: Select CVM self-built as the access method.
CDB instances: Select CDB as the access method.

Migrating to MySQL

Note:
The version requirements for each database migration are as follows:
The data migration module does not support migrating out of cloud when the source is the TDSQL-C MySQL database type. If you have such cloud migration needs, please use the data sync module.
MySQL/TDSQL MySQL/MariaDB/TDSQL-C MySQL/TDSQL MySQL: The target database version must be equal to or later than the source database version, distinguished by the major version number. For example, 5.6.x can be migrated to 5.6.x, 5.7.x, or later versions.
