Hi, If it's truly anycast it should only be easier, I would simply: - stop announcing the anycasted prefix at node #1 - once you see no queries anymore: convert and test - after finishing: switch on routing - repeat untill node #last Unless you have bizarre performance complications, above would be more safe than converting an active node. Did I maybe misunderstand the question? Or did you mean: "how to convert from pdns with a transactional SQL backend to a conventional DNS setup with Knot" ..? Leo
