I am not sure if I understood your problem correctly but it looks like the
data comes late and hence the replication doesn't happen. You can try
specifying the "delay" attribute on source cluster in feed definition to
start replication with delay. e.g.

<cluster name="corp1" type="source" delay="hours(7)">
    <validity start="2010-01-01T00:00Z" end="2020-01-01T02:00Z"/>
    <retention limit="days(5)" action="delete"/>
<cluster name="corp2" type="target">
    <validity start="2010-01-01T00:00Z" end="2020-01-01T02:00Z"/>
    <retention limit="days(7)" action="delete"/>
