When you create a Query on the Enterprise that Query will be replicated down to the Domain Manager.
Sometimes customers will run a preview on a Query and save the results.
When replication tries to replicate these results down to the Domain Manager you can get the following error:
Error replicating ca_query_version.
The best way to resolve this is to go to the Enterprise and delete all saved Query previews.
If you don't know where they are you can do a:
select qd.label as Query_Name, qv.label as Query_Version_Name from ca_query_version qv, ca_query_def qd
where qv.query_uuid = qd.query_uuid
and it will list all the Queries and the name of the Saved results, so you can find them and delete them in the GUI.
