POST /svm/migrations

Introduced In: 9.10

Creates an SVM migration operation. This API must be executed on the destination cluster. This API creates an SVM on the destination cluster and preserves the SVM's identity specified in the source cluster. Optionally, you can specify the aggregate list for creating the volumes, and IPspace. You can perform pre-checks to verify if SVM migration is possible, by setting the "check-only" option to "true". By default the values for auto-source-cleanup and auto-cutover is true.

Required properties

  • source.svm.name or source.svm.uuid - Source SVM name or source SVM UUID.

  • source.cluster.name or source.cluster.uuid - Source cluster name or source cluster UUID

Optional properties

  • destination.ipspace.name or destination.ipspace.uuid - Destination IP Space name or UUID where the vserver will be migrated to.

  • destination.volume_placement.aggregates - List of aggregates where the migrating volumes should go on the destination.

  • auto_cutover - Option to specify whether to perform cutover automatically. Default is true.

  • auto_source_cleanup - Option to specify whether to perform souce cleanup automatically. Default is true.

  • check_only - Option to perform all the prechecks for migrate without actually starting the migrate. Default is false.

  • vserver migrate start

Parameters

Name Type In Required Description

return_timeout

integer

query

False

The number of seconds to allow the call to execute before returning. When doing a POST, PATCH, or DELETE operation on a single record, the default is 0 seconds. This means that if an asynchronous operation is started, the server immediately returns HTTP code 202 (Accepted) along with a link to the job. If a non-zero value is specified for POST, PATCH, or DELETE operations, ONTAP waits that length of time to see if the job completes so it can return something other than 202.

  • Default value: 1

  • Max value: 120

  • Min value: 0

return_records

boolean

query

False

The default is false. If set to true, the records are returned.

  • Default value:

Request Body
