Domain transfer order fails :
Registering domain in external source failed. An attempt to call external for name servers failed. An attempt to call external for name servers failed. Parallels Operations Automation error #error_code #2007, extype_id #205, module_id #ResourceManagement, Subscription #<SUBSCRIPTION_ID> already exists.. Domain status:Prepared Service Creation Failed: Name Servers acquiring failed.
Previous error can be seen in the subscription service status history which is:
Registering domain in external source failed. An attempt to call external for name servers failed. Parallels Operations Automation error #extype_id #1, module_id #DnsZoneMutator, javax.persistence.PersistenceException: org.hibernate.exception.ConstraintViolationException: could not execute statement. Domain status:Prepared
The initial root cause of the issue is that the domain already exists in OA. There are several issue involved:
a) #PBA-67633 "Domain transfer cannot be completed if first request to OA failed". This bug causes an error "Subscription already exists".
b) #POA-92125 "addDomainRequest is failing if domain with same name with A record in root exists", fixed in OA 6.0.3
c) #POA-97652 "Duplicate domains considered parents of each other", fixed in OSA 7.1
