Migration should allow the update of element definition versions.

...

Solution 1: add a flag in composition definition

The validation is active by default.

To disable the validation:

• define the flag "migrateMajorVersion" as a property into the new composition definition with default false. 

  Code Block
  language yml
  org.onap.policy.clamp.acm.AutomationCompositionElement: version: 1.0.1 derived_from: tosca.nodetypes.Root properties: provider: type: string required: false      migrateMajorVersion: type: boolean required: false default: false metadata: common: true description: Allow to migrate to major version      startPhase: type: integer required: false constraints: - greater-or-equal: 0 metadata: common: true description: A value indicating the start phase in which this automation composition element will be started, the first start phase is zero. Automation composition elements are started in their start_phase order and stopped in reverse start phase order. Automation composition elements with the same start phase are started and stopped simultaneously

  
  

• use the property "migrateMajorVersion".

  Code Block
  language yml
  onap.policy.clamp.ac.element.Policy_AutomationCompositionElement: version: 1.2.4 type: org.onap.policy.clamp.acm.PolicyAutomationCompositionElement type_version: 1.0.0 description: Automation composition element for the operational policy for Performance Management Subscription Handling properties: provider: Ericsson startPhase: 0        migrateMajorVersion: false

  
  

Solution 2: add a property in properties file:

The validation is active by default.

To disable the validation, add migrate.validation.majorversion.enable property and set to false into properties file.

migrate:
  validation:
    majorversion:
      enable: false

elements:

Implementation of the Participant using AcElementListenerV1

Participant has to implement the "migrate" method.

...

var automationComposition = participantIntermediaryApi.getAutomationComposition(instanceId);
var compositionId = automationComposition.getCompositionId();
var acElementDefinitionsFrom = participantIntermediaryApi.getAcElementsDefinitions(compositionId);
var acElementDefinitionFrom = acElementsDefinitionsFrom.values().stream()
    .filter(el -> el.getAcElementDefinitionId().getName().equals(element.getDefinition().getName())).findFirst().get();
var outPropertiesFrom = acElementDefinitionFrom.getOutProperties();

var acElementDefinitionTo = participantIntermediaryApi.getAcElementDefinition(compositionTargetId, element.getDefinition());
var outPropertiesTo = acElementDefinitionTo.getOutProperties();

Implementation of the Participant using AcElementListenerV2

All data are already available into the respectively Objects.
