Before You Start

Before using SMS, you must:

• Confirm that you have the required permissions.

  Your target account must have the permissions required to use SMS and its dependent cloud services.

• Confirm that your source server OS is supported by SMS.
  You can learn more about supported OSs from the following links:

  • Supported Windows OSs
  • Supported Linux OSs
• Determine which region you want to migrate to.

  You need to know which region you want to migrate to. When you create a migration task, the region specified in the default migration template is used as the target region. You need to confirm that the region is correct.

• Read the SMS precautions.

  SMS Precautions

• Back up data on the target server disks, and ensure that the disks can be formatted.

  Disks on the target server will be formatted and re-partitioned based on the source disk settings during the migration. If you choose to use an existing server on the cloud as the target server, make sure that any data on the target server has been backed up and that the disks can be formatted.

• (Recommended) Disable any software in conflict with SMS on the source server.

  Any antivirus or conflicting software on the server server may prevent the SMS-Agent from start. If you are not sure whether there is a software conflict with the SMS-Agent, back up your data before the migration.

• Confirm that your account balance is enough.
  • SMS is a free service, but you will still be billed for any other resources used during the migration. For details, see Billing.
• Know when the target server can be operated.

  Do not operate the target server before the migration is complete, such as renewing the target server or changing its billing mode.

• Learn where to find the solutions to common migration issues.

  If you encounter any problem during the migration, try to solve the problem by referring to FAQs.
