Guide to Migrating Tencent Cloud CVM Images to Alibaba Cloud ECS Using the SMC Client

Document Background: To support cross‑cloud deployment, the business needs to quickly convert a Tencent Cloud CVM instance into an Alibaba Cloud ECS image, reducing deployment time and cost.

Intended Audience: Business SREs, DBAs, and resource‑delivery SREs. The actual migration steps must be performed by resource‑delivery SREs; business SREs are prohibited from operating due to cost and sub‑account permission concerns.

Migration Cost: Choose either bandwidth‑based or traffic‑based billing. Currently the three‑network model uses traffic billing, and migrating a 500 GB image costs roughly 40–50 CNY.

Operation Flow Overview: The process consists of downloading the SMC client, preparing the source server, creating a migration task in Alibaba Cloud, starting the task, and monitoring progress.

Step 1 – Download the SMC client: Obtain go2aliyun_client2.6.0_linux_x86_64.zip from the Alibaba Cloud console (or via the direct download link).

Step 2 – Import the migration source:

2.1 Upload the zip package to the Tencent Cloud server that will be migrated (e.g., using rz ).

2.2 Unzip the package:

unzip go2aliyun_client2.6.0_linux_x86_64.zip

2.3 Enter the extracted directory:

cd go2aliyun_client2.6.0_linux_x86_64

2.4 Add execution permission and run the client, manually entering access_id and secret_key (recommended for security; they can also be placed in user_config.json ):

chmod +x go2aliyun_client && ./go2aliyun_client

Step 3 – Create the migration task: In the Alibaba Cloud SMC console, click “Create Migration Task” (as shown in the UI screenshot), select the target region, set the target type to “Cloud Server Image”, and optionally configure transfer speed limits (useful for bandwidth‑based billing).

Step 4 – Start the migration task: Choose “Execute Immediately”, confirm, and the client will receive the start signal and begin the migration.

Step 5 – Monitor migration progress: View real‑time progress in the Alibaba Cloud console until the migration completes.
