Server Migration Center:CreateReplicationJob

Last Updated:Mar 03, 2024

Creates a migration job for a source server.

Operation description

Usage notes

  • You can create migration jobs only for source servers that are in the Available state.
  • Each source server can be associated with only one migration job that is in the Ready, Running, Stopped, Waiting, InError, or Expired state.
  • You can create a maximum of 1,000 migration jobs within each Alibaba Cloud account.
  • If you migrate a source server to an image, you must specify the ImageName, SystemDiskSize, and DataDisk parameters.
  • If you use a virtual private cloud (VPC) to migrate data, the VSwitchId parameter is required and the VpcId parameter is optional.
  • Server Migration Center (SMC) allows you to migrate source servers to Docker container images. This allows you to migrate containerized applications in a cost-effective way.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

Request parameters

ParameterTypeRequiredDescriptionExample
RegionIdstringYes

The ID of the Alibaba Cloud region to which you want to migrate the source server.

ScheduledStartTimestringNo

The time when you want to run the migration job. The time must meet the following requirements:

  • The time must be specified in the ISO 8601 standard in the YYYY-MM-DDThh:mm:ssZ format. For example, 2018-01-01T12:00:00Z specifies 20:00:00 on January 1, 2018 (UTC+8).
  • The value must be within 30 days after the current time.
Note If you do not specify this parameter, you must manually start the migration job after the job is created. You can call the StartReplicationJob operation to start the migration job.
2019-06-04T13:35:00Z
ValidTimestringNo

The time when the migration job expires. You can schedule the migration job to expire 7 to 90 days after the job is created.

  • The time must be specified in the ISO 8601 standard in the YYYY-MM-DDThh:mm:ssZ format. For example, 2018-01-01T12:00:00Z specifies 20:00:00 on January 1, 2018 (UTC+8).
  • If you do not specify this parameter, the migration job does not expire.
  • After a migration job expires, the job state changes to Expired. SMC retains the migration job for seven days after the job expires. After the job is retained for seven days, SMC deletes the migration job.

By default, a migration job is valid for 30 days after it is created.

You must set this parameter if you use a VPC to migrate data.

vsw-bp1ddbrxdlrcbim46****
ReplicationParametersstringNo

The parameters of the replication driver. The parameters must be specified as key-value pairs in the JSON format. The keys are fixed for each type of replication driver. The JSON string can be up to 2,048 characters in length.

A replication driver is a tool that is used to migrate a source server to an intermediate instance. The parameters vary based on the replication driver type. If you use a Server Migration Tool (SMT) driver, you can specify the following parameters:

  • bandwidth_limit: the maximum bandwidth for data transmission.
  • compress_level: the compression ratio of data to be transmitted.
  • checksum: specifies whether to enable checksum verification.

For more information about replication drivers, see the response parameter SourceServers.ReplicationDriver of the DescribeSourceServers operation.

{"bandwidth_limit":0,"compress_level":1,"checksum":true}
NetModeintegerNo

The network mode for data transmission. Valid values:

  • 0: Data is transmitted over the Internet. Make sure that the source server can access the Internet.
  • 2: Data is transmitted over a VPC. If you specify this value, you must specify the VSwitchId parameter. You do not need to specify the VpcId parameter because the value of the VpcId parameter can be retrieved based on the value of the VSwitchId parameter.

Default value: 0

0
RunOncebooleanNo

Specifies whether to disable incremental migration for the source server. Valid values:

  • true: creates a migration job that runs only once. This is the default value. Incremental data of the source server is not synchronized.
  • false: creates an incremental migration job. In this case, you must specify the Frequency parameter. SMC synchronizes incremental data of the source server to Alibaba Cloud at the specified frequency. You can use an incremental migration job to synchronize incremental data from the source server to Alibaba Cloud without the need to interrupt your business. A full data image is generated for the source server when the job is running.
Note You can specify this parameter only when you create a migration job. The parameter value cannot be changed after the migration job is created.
true
FrequencyintegerNo

The interval at which SMC synchronizes incremental data to Alibaba Cloud. Unit: hour. Valid values: 1 to 168.

This parameter is required if you set the RunOnce parameter to false.

By default, this parameter is empty.

12
MaxNumberOfImageToKeepintegerNo

The maximum number of images retained for the incremental migration job. Valid values: 1 to 10.

This parameter is required if you set the RunOnce parameter to false.

By default, this parameter is empty.

10
InstanceTypestringNo

The type of the intermediate instance.

You can call the DescribeInstanceTypes operation to query the ECS instance types.

  • If you specify this parameter, SMC creates an intermediate instance of the specified instance type. If the specified instance type is unavailable, the migration job fails to be created.
  • If you do not specify this parameter, SMC selects an available instance type in a specific order to create an intermediate instance. For more information, see the "How does SMC create an intermediate instance?" section of the SMC FAQ topic.
