Yes, in the sense that the successor Event keeps the recurrence configuration. For example, in the GUI smoke test the original occurrence showed Every Thursday, and after rollover the successor Topic also showed Every Thursday with the date advanced to the following week.
What this PR doesn’t add is a separate cross-Topic series relationship linking the completed Topic and its successor. The completed Topic becomes the one-off archived occurrence, while the successor carries the recurrence forward. An explicit series/parent relationship between those Topics could be a separate enhancement if that proves useful.
It doesn’t automatically carry every guest/attendee into the new Event.
The successor only inherits people who were going with the recurring/series RSVP enabled. Someone who RSVP’d going only to the individual occurrence remains on the completed Topic and isn’t added to the successor.
So at present the existing choice to RSVP to the series effectively acts as the opt-in for being carried into future successor Events, rather than there being another site setting controlling it.
