Unfortunately my experience has been the opposite. I am to this day fighting with errors
produced when we run samba-tool dbcheck --cross-ncs --fix.

other than that everything seems to work as advertised but it was a long road getting there.

It might have something to do with starting this journey in the 4.7/4.8 timeframe but I think
if I had it to do again I would most likely start a new domain.
