Description:  
After discussions with the IT partner gateway team, we gathered the following information:

• Subscription 15563275 was moved from org 18479847 to org 4364786.
• Splunk logs confirm the transfer in IT gateway

   host=*gateway*-prod* index=rh_middleware "action=entitlement-transferred" 

  Logs:
  {{Publishing message: UmbMessage(body=EntitlementTransferredMessage
  Unknown macro: {cloudIdentifiers=AwsIdentifiersUnknown macro}
  , redHatSubscriptionNumber=null, action=entitlement-transferred, sourceRhAccountId=18479847, destinationRhAccountId=4364786}, headers={}, destination=VirtualTopic.services.partner-entitlement-gateway)

• SWATCH side transfer logs were found using the query:  
   

   index=rh_rhsm namespace=rhsm-prod source="swatch-contracts" "ContractUMBMessageConsumer" | rex  field=message "sourceRhAccountId\":\"(?<sourceRhAccountId>\d+).*destinationRhAccountId\":\"(?<destinationRhAccountId>\d+)"| search "entitlement-transferred" | table _time _raw sourceRhAccountId destinationRhAccountId 

Done:  
1. Implement logic in swatch-contract to handle contract/subscription changes between organizations.
2. Add IQE swatch-contract component test to cover this use case.

3. Sync the orgs that had issues in prod
