Unfortunately, there is not an automatic way for you to pull out issues in sync but here is an SQL query which you can use:
SELECT LR.issue_urn AS this_issue, RR.issue_urn AS remote_issue FROM twin_trace TT LEFT JOIN replica LR ON TT.local_replica_id = LR.id LEFT JOIN replica RR ON TT.remote_replica_id = RR.id JOIN relation R ON TT.relation_id = R.id WHERE R.name IN ('JIRA_SERVER_to_JIRA_CLOUD');
We are looking forward on implementing this feature, but I hope you find this is helpful in the meantime.
