What Configuration Items Do I Need to Modify for the Target Server After the Migration Is Complete?

Background

When you use SMS to migrate a source server, the target server configurations will be automatically modified based on your settings in the migration task. For details about the items modified, see What Are the Differences Between the Target and Source Servers After the Migration? You also need to modify the configurations of the target server based on service requirements after the migration. These auto or manual modifications are made to ensure that the target server can run normally and your services match your business processes and security standards. Here we list some configuration items you may need to modify based on service requirements.

The items listed here need to be modified after the migration and service cutover are complete.

Synchronizing NTP Clocks (Recommended)

If the system time and hardware time on a Linux target server are inconsistent with those on the source server, rectify the fault by referring to What Do I Do If the Source Server's Clocks Are Not Synchronized to the Target Server?

Modifying Network Configurations (Recommended)

To ensure compatibility with Huawei Cloud, SMS modifies the network configurations of target servers. After the service cutover is complete, you can modify the network configuration files about NICs, DNS, SSH, and other items based on service requirements.

Clearing Residual SMS Installation Packages (Recommended)

During a migration, SMS migrates all data on the source server to the target server, including the SMS migration software. After the migration is complete, you are advised to delete the SMS software from the target server.

Modifying Security Group and Policy Settings (Recommended)

  • During a migration, the security group of the target server needs to allow traffic from the source server over certain ports based on the OS type and migration method. Ports 8899, 8900, and 22 are required for a Windows block-level migration, ports 8900 and 22 are required for a Linux block-level migration, and port 22 is required for a Linux file-level migration. After the migration is complete, it is essential for you to review and adjust the security group settings as necessary. It is best to disable high-risk ports.
  • During the migration, it is necessary to disable the firewall or security software. Once the migration is complete, you need to reconfigure the security protection policy.

Configuring Software Sources (Optional)

SMS does not automatically modify software sources for target servers, such as yum, apt, and zypper repositories. After the migration is complete, you can configure proper software sources based on service requirements.

Clearing Components and Services from Source Platforms (Optional)

After a server is migrated from another cloud platform, there may be leftover components or services from the source platform, for example, Alibaba's Cloud Shield or platform services. You can determine whether to uninstall these components or services as required.

Installing Huawei Cloud Password Reset Plug-in (Optional)

To use the password reset function on the ECS console, you can install the Huawei Cloud password reset plug-in to reset the password with a few clicks. For more information, see:
