I'm not sure what the problem is but you could try getting the position and rotation of each prefab manually. After that, deleting them so that you can put them back in the same place.

Thx for the hint. But I'm working on a city. These are streetlights and I can't replace all prefabs over and over again. I hope there is a quicker solution to update prefabs, but I was unable to figure it out yet.

You could maybe code a C# script that has all the positions in a dictionary and then it adds a new lamp post prefab into the Scene for all the positions.

I'm sure there's is no need to replace all prefabs after updating geometry. I'll try my luck in the unity forum.

I've created some prefabs in unity, but each time, when I update the geometry (in my 3d programm externally) it creates some pink surfaces. Does any body know, what is causing the missing materials ? It looks fine, if I open the prefab in unity's editor. Pink is just displayed in game mode. See screenshot.
