You don’t need to invoke the Configuration Wizard per se, it will naturally invoke itself just to make sure that everything is kosher on the DB level anyways.
The CW should launch automatically on the tail end of each Additional Poller install so just let it launch and sync itself with the rest of the engineIDs and that should address that part.
Once the primary and all FOUR additional pollers have run and then have thus run through the CW then all 5 servers should then be in sync with each other.
