Do you guys have any experience with that?
I would switch all at the same time. 8.4 to 9.0 was anticipated to be a thing, but it never was. Customers switching to 9 started from fresh or created a 9 resource and copied the data. Connecting 8.4 to 9.0 should be possible, but I'd say it is pretty untested. I'd try to avoid it.
