Best Way to Move Servers/Users within the Hierarchy

Hi,

So before I arrived at my present position, the Notes network was created so that all objects in our Cambridge office were certified as: CN/O

I’d like to change this to CN/OU/O by creating a new OU certifier and migrating everything over. The potential problem here is that there are several servers, including the administration server for the PAB, already setup using CN/O

What’s the best method to approach this? Moving the users shouldn’t be much of a hassle, but I’m more worried about the servers.

Is it possible to create new servers with the same CN but a different DN? For example, to have serverA/O and serverA/OU/O and then migrate databases and users over from one to the other?

Any suggestions are appreciated,
