RequestStateChange method of the Msvm_MigrationJob class
Requests that the state of the migration job be changed to the specified state. Invoking the RequestStateChange method multiple times can result in earlier requests being overwritten or lost. If 0 is returned, then the task completed successfully. Any other return code indicates an error condition.

TimeoutPeriod [in]
A timeout period that specifies the maximum amount of time that the client expects the transition to the new state to take. The interval format must be used to specify the timeout period. A value of 0 or Null indicates that the client has no time requirements for the transition. If this property does not contain 0 or Null and the implementation does not support this parameter, a return code of 4098 (Use Of Timeout Parameter Not Supported) must be returned.
