PATCH /svm/migrations/{uuid}

Introduced In: 9.10

Actions that can be performed during an SVM migration.

  • vserver migrate pause

  • vserver migrate resume

  • vserver migrate cutover

  • vserver migrate source-cleanup

Parameters

Name Type In Required Description

uuid

string

path

True

SVM migration UUID

action

string

query

False

The pause action pauses the SVM migration. This action stops data transfer and configuration replication. This operation must be performed on the destination cluster. The resume action resumes an SVM migration from a paused or failed state. If the SVM migration is in a cleanup_failed state, volume placement is ignored. This operation must be performed on the destination cluster. The cutover action triggers the cutover of an SVM from the source cluster to the destination cluster. The source_clean up action performs a clean up of the SVM on the source cluster.

  • enum: ["pause", "resume", "cutover", "source_cleanup"]

auto_cutover

boolean

query

False

Optional property that when set to true automatically performs cutover when the migration state reaches "ready for cutover".

  • Default value: 1

auto_source_cleanup

boolean

query

False

Optional property that when set to true automatically cleans up the SVM on the source cluster after the migration cutover.

  • Default value: 1

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

Request Body

Name Type Description

auto_cutover

boolean

Optional property that when set to true automatically performs cutover when the migration state reaches "ready for cutover".

auto_source_cleanup

boolean

Optional property that when set to true automatically cleans up the SVM on the source cluster after the migration cutover.

check_only

boolean

Optional property that when set to true performs only migration pre-checks not the actual migration.

current_operation

string

destination

destination

Destination cluster details for the SVM migration.

ip_interface_placement

svm_migration_ip_interface_placement

Optional property used to specify the list of source SVM's IP interface and network port pairs in the destination for migrating the source SVM IP interfaces. Note that the SVM migration does not perform any reachability checks on the IP interfaces provided.

last_failed_state

string

Indicates the state of the migration.

last_operation

string

messages

array[messages]

Errors and warnings returned/displayed during migration.

point_of_no_return

boolean

Indicates if the migration has progressed beyond the point of no return. When true, the migration cannot be aborted or paused. When false, the migration can be paused or aborted.

restart_count

integer

Number of times migrate restarted the transfer, for example, rollback to transfer after starting the cutover.

source

source

Source cluster details for the SVM migration.

state

string

Indicates the state of the migration.

throttle

integer

Optional property to specify a throttle value in KB/s for each individual volume transfer. Defaults to 0 if not set, which is interpreted as unlimited. The minimum throttle value is 4 KB/s, so if you specify a throttle value between 1 and 4, it will be treated as if you specified 4.
