Yes, you can migrate a domestic cloud server instance to an overseas region, but the process involves several technical and compliance considerations.
Key Considerations:
- Data Transfer & Compliance – Ensure compliance with data sovereignty laws (e.g., GDPR, CCPA) when moving data across regions. Some countries restrict cross-border data transfers.
- Network Latency & Bandwidth – Cross-region migration may require high-bandwidth connections to minimize downtime.
- Instance Compatibility – The target region must support the same OS, instance type, and configurations.
- DNS & IP Changes – Public IPs may differ, requiring DNS updates or elastic IP reassignment.
Migration Steps:
- Create a Snapshot – Take a snapshot of the domestic server’s system disk and data disks.
- Copy to Overseas Region – Upload the snapshot to the target region (may require manual transfer via object storage).
- Launch New Instance – Use the snapshot to create a new instance in the overseas region.
- Reconfigure Network & Security – Update firewall rules, load balancers, and DNS settings.
Example Scenario:
A company in China running a web application on a domestic cloud server needs to expand to Southeast Asia for lower latency. They:
- Take a snapshot of the server.
- Upload it to Tencent Cloud’s Singapore region.
- Launch a new instance and update DNS to point to the new IP.
Tencent Cloud Services for Migration:
- Cloud Block Storage Snapshot – For backing up disks.
- COS (Cloud Object Storage) – To transfer snapshots across regions.
- VPC Peering & Direct Connect – For secure cross-region networking.
- Server Migration Center (SMC) – Automates large-scale migrations.
If the migration involves large-scale databases, consider using Tencent Cloud Database Migration Service (DCS) for minimal downtime.
