This document describes how to migrate the system and applications from a source server in your IDC or a cloud platform to CVM through the online migration in private network mode in the CVM console.
Compared with the public network mode, migration over the private network has a higher migration transfer speed, which can significantly improve the migration efficiency. Plus, it doesn't restrict the public network access capability of the source server, making the migration configuration more flexible.

Choose the appropriate migration mode according to the network environments of your source servers and destination CVMs.
You can choose to transfer over the public and private network. The private network mode applies to three scenarios. Each migration mode or scenario has different network requirements for source servers and destination CVMs. If both source servers and destination CVMs can access the public network, you can use the default mode for migration. If source servers or destination CVMs cannot directly access the public network, you need to establish a connection between them through VPC Peering Connection, VPN Connections, Cloud Connect Network, or Direct Connect before using the private network mode for migration.
Before migration, you need to check the following configuration based on the actual conditions:
Linux source server |
|
---|---|
Destination CVM (optional) |
|
Note
- You can use tool commands such as
sudo ./go2tencentcloud_x64 --check
to automatically check the source server.- By default, the go2tencentcloud migration tool automatically performs checks upon launch. To skip checks and perform forced migration, configure
Client.Extra.IgnoreCheck
totrue
in the client.json file.- For more information on the go2tencentcloud migration tool, see Compatibility and Tool Configuration Description.
go2tencentcloud.zip
to the source server and run the following command to enter the corresponding directory.go2tencentcloud.zip
and enter the directory.unzip go2tencentcloud.zip
cd go2tencentcloud
ii. Run the following commands in sequence to decompress `go2tencentcloud-linux.zip` and enter the directory.
unzip go2tencentcloud-linux.zip
cd go2tencentcloud-linux
NoteThe files in the
go2tencentcloud
directory will not be migrated. Do not place the files to be migrated in this directory.
Client.Net.Proxy.Ip
and Client.Net.Proxy.Port
in the client.json
file to the IP address and port of the network proxy.Client.Net.Proxy.User
and Client.Net.Proxy.Password
.chmod +x go2tencentcloud_x64
sudo ./go2tencentcloud_x64
ii. Enter the SecretId
and SecretKey
of the account API access key obtained in Prerequisites and press Enter.
If the information in the following figure is displayed in the window of the migration tool, the migration source has been imported to the console successfully, and you can go to the console to view it:
You can log in to the CVM console and enter the online migration page to view the imported migration source, whose status is Online.
If "Import source server successfully" isn't displayed, the migration source failed to be imported, and you can view the log (which is the logs/log
file in the migration tool directory by default) for troubleshooting. Then, run the migration tool to import the migration source again.
NoteAfter the migration source is imported successfully, don't close the migration tool in the instance until the migration task is completed; otherwise, the migration task can't be completed after the migration source becomes offline.
Go to the online migration page in the CVM console to create a migration task.
i. Log in to the CVM console, go to the online migration page, and click Create Migration Task on the right of the desired migration source.
ii. In the Create Migration Task pop-up window, configure the task as instructed in Migration Task Configuration Description.
For example, to migrate a Linux source server to the Shanghai region of Tencent Cloud in private network mode and generate the destination CVM image, you can configure the migration task.
Start the migration task
NoteYou can skip this step if your task is scheduled, which will automatically start running at the scheduled execution time.
After creating a migration task, you can click the Migration Task tab to view the task.
You can click Start/Retry on the right of the task to start it, click OK in the pop-up window, and the task status will become Migrating.
NoteThe time required for data transfer depends on the size of the data on the source server, network bandwidth, etc. Please wait for the migration process to end. The migration tool supports checkpoint restart for data transfer.
If you have any questions or the migration has an exception, see FAQs about Service Migration or Contact Us.
