Overview
Scenarios
This practice describes how to migrate data from RDS for MySQL to DDM using Data Replication Service (DRS), including how to create an RDS for MySQL instance and a DDM instance on Huawei Cloud, and how to migrate data over the VPN network.
Prerequisites
- You have a Huawei Cloud account.
Service List
- Virtual Private Cloud (VPC)
- Virtual Private Network (VPN)
- RDS
- Distributed Database Middleware (DDM)
- Data Replication Service (DRS)
- Data Admin Service (DAS)
Deployment Architecture
In this example, the source is a Huawei Cloud RDS for MySQL instance and the destination is a DDM instance. Data is migrated from the source to the destination over a VPN.
Constraints
- Before data migration, you need to stop your workloads to ensure data integrity.
- The new RDS for MySQL instance must be of the same version as the source RDS for MySQL instance.
Notes on Usage
- The resource planning is for demonstration only. Adjust it as needed.
- The end-to-end test data is for reference only.
