2. SMS Terms of Service

2.1 Service Content

This Service helps you migrate servers from on-premises infrastructure, private clouds, or public clouds to Huawei Cloud.

2.2 Collection and processing of your personal information

For the entire service process, you understand and agree that Huawei Cloud is entitled to collect, use, and process your personal data in accordance with the Privacy Statement (

2.3 Processing Your Content Data

You understand and agree that Huawei Cloud is entrusted to collect and use your server information for the purposes of providing this Service. The information includes the host names, IP addresses, and MAC addresses of your servers. Huawei Cloud provides a controllable data deletion mechanism for you. The aforementioned information will be deleted when you confirm that your migration is complete and delete migration tasks on the console of this Service. Otherwise, deleting the information will cause migration failures. You understand that the above information is necessary to provide services to you. If you choose not to provide or authorize us to collect and use of the above information, Huawei Cloud will not be able to provide you with this Service.

You understand and agree that you and/or your end users entrust us to process your source server information and the data contained in the source servers in any format when using SMS. You have full ownership and control over the data. You are responsible for the legality of the source and acquisition of such data as well as the legality of migrating it from source servers to target servers, including but not limited to the compliance of cross-border data transfer. Huawei Cloud is entrusted to process your data in order to migrate source server OSs and disk data to target servers on Huawei Cloud. Your aforementioned data will be processed within the Republic of Singapore. You can control your aforementioned data at your own discretion.

2.4 Cooperation You Need to Provide

Creating agent images

Security standards iterate and security vulnerabilities develop over time. Before the migration, you need to create agent images and perform security scanning and hardening on the images. SMS provides standard agent images for you to test SMS availability. Do not use them to migrate your services.

Configuring security groups of target servers

SMS requires that traffic from source servers be allowed over specified ports on target servers. You need to configure security groups of target servers to allow only access from source servers and take other necessary measures to ensure migration security.

2.5 Service Pricing

SMS is free, but you are billed at standard rates for the EVS disks, EVS disk snapshots, and data transfer generated during the migration process.

2.5.1 EVS disk

SMS creates and attaches a 40 GB EVS disk to each target server temporarily during the migration. These EVS disks are billed on a pay-per-use base. After the migration is complete, these EVS disks will be released. Do not delete these EVS disks during the migration or change their billing modes to yearly/monthly, or the migration will fail.

2.5.2 EVS disk snapshot

SMS creates snapshots of target servers for service cutover, data synchronization, and target server clones.

2.5.3 Data transfer

Traffic is generated during the migration and is billed as follows:

1) If the source public IP address is billed by bandwidth and you use the fixed bandwidth for migration over the Internet, the traffic you used will not be billed.

2) If the source public IP address is billed by traffic and you migrate data over the Internet, the price is calculated by multiplying the unit price of the traffic by the amount of data migrated. For details about the unit price of the traffic, contact the provider of the source public IP address. The amount of data migrated is the actual usage of disks on source servers.

For example, if the public IP address of a source server is billed by traffic, the unit price is $0.15 USD/GB, and the total disk size of a source server is 500 GB (including 300 GB of used space), the cost is $45 USD (0.15 x 300). Note that this fee is billed by the provider of the source public IP address.

3) If you use Direct Connect or Virtual Private Network (VPN) for migration, the cost depends on the price of your Direct Connect or VPN connections.

2.6 Disclaimer

2.6.1 License invalidity

After OSs, applications, and files are migrated from source servers to target servers, the SIDs and MAC addresses of the servers will change, and some OS or application licenses may become invalid. SMS is not responsible for this type of issue. You can contact the image providers of your target servers to activate Windows Oss and update or obtain application licenses at your own expense.

2.6.2 Fees or data damage caused by your operations

Before a migration is complete, do not perform operations on the OS or disks of the target server, including but not limited to changing the OS and reinstalling the OS. SMS is not responsible for any fees or data damage incurred.

2.6.3 Target server disk formatting

During the migration, disks on the target server are formatted and re-partitioned based on the source disk settings. Any existing data on the target server will be lost. Before the migration, make sure you have backed up any data on the target server that you need to save and ensure that the disks can be formatted.

2.6.4 Migration errors caused by source servers

SMS is not responsible for migration errors caused by source server problems, including but not limited to damaged hardware (such as damaged disks and NICs), improper configurations, or software incompatibility (such as incompatible OSs and applications), damaged data files, heavy service traffic, and slow network speed. You can fix these problems by yourself, but if any such problems persist, you can contact Huawei Cloud for assistance. Huawei Cloud will make every effort to assist in resolving the problems but does not guarantee all possible problems can be resolved. Many problems on a source server may lead to migration errors, for example:

1) A faulty source server OS. For example, a Windows startup file is damaged or missing.

2) An incorrectly configured source server OS. For example, GRUB or fstab may be incorrectly configured on the source server.

3) Source server network problems. For example, the source server cannot access the Internet, the network speed is too slow, or the SSH connection or firewall is faulty.

4) Slow I/O on source server disks, too much incremental data, scattered effective clusters (on Windows), or too many small files (on Linux). These problems can slow down the migration or synchronization progress.

5) An incompatible source platform service or software

6) The Agent is disabled by a source platform service or software, or the I/O monitoring is disabled by antivirus software on the source server.

2.6.5 If your target servers on Huawei Cloud cannot be started after the migration is complete, Huawei Cloud can provide technical support to help you solve problems, but does not promise that the all possible problems can be resolved.

2.6.6 To ensure compatibility with Huawei Cloud, SMS modifies the system configurations of target servers. SMS can ensure data consistency before and after the migration but cannot ensure that your services run properly after the migration. You need to modify related service configurations afterwards.

2.6.7 You are advised not to add data to target servers before the service cutover or to source servers after the service cutover. If new data is generated on both your source and target servers after the service cutover, SMS cannot combine data on the source and target servers. If you want to combine the new data on the source and target servers, you must design your own solution.

2.7 Other Special Notes

2.7.1 Log printing

During the migration, SMS prints logs on the source and target servers. After the migration is complete, SMS automatically deletes the logs on the target server, and you need to manually delete the logs from the source server. The logs contain the IP addresses and disk, mounting, and fstab details. Logs on the source server will not be uploaded to SMS.

2.7.2 Configuration modification

To ensure that target servers can be started properly after the migration is complete, SMS modifies the boot, network, and system configurations of the servers.

2.7.3 Cross-border data transfer

SMS is only responsible for point-to-point data migration from source servers to target servers. It is unaware of the data migrated. If your server data needs to be migrated across borders, you must ensure the compliance of the migration.
