All Implemented Interfaces:

info.magnolia.module.delta.Task

public class ChangeDataDmsReferenceToDamMigrationTask
extends info.magnolia.module.delta.AbstractRepositoryTask

This task is responsible for changing the old DMS/Data/... references to DAM references.
Steps:

 Iterate the list of contentPathsList,
  Perform a JCR query that search for properties named 'imgUUID' and return the related node.
  Iterate the query result list
  For every Node,
   If the identifier exist in the dam repository as an Asset.
    Transform the identifier as an Asset composite id (assetProviderId:AssetIdentifier)
    Update the 'img' link to the corresponding path.
   Else
    Remove the property.
 

 Normal handling:
 Move from:
  property sv:name="img" sv:type="String"
  value = /demo-project/img/bk/Stage/v-light-4
  property sv:name="imgUUID" sv:type="String"
  value = 4c291aa5-9807-4bbe-b372-ce523f82e600
 To:
  property sv:name="imgUUID" sv:type="String"
  value = jcr:4c291aa5-9807-4bbe-b372-ce523f82e600
 
 OR
 Move from:
  property sv:name="img" sv:type="String"
  value = dms
  property sv:name="imgUUID" sv:type="String"
  value = 4c291aa5-9807-4bbe-b372-ce523f82e600
 To:
  property sv:name="img" sv:type="String"
  value = jcr:4c291aa5-9807-4bbe-b372-ce523f82e600
 
 Specific handling:
  In case of the UUID does not exist any more, remove properties.
