If so and there is a lot of data to copy what we have done in the past is set up the new server as an additional server, replicate all the data over (you may need to add new server to all db ACLs)do one final replication then stop domino on the first server, copy over the notes.ini and server id, change server IP address and bring up new server.
I like do the just about the same thing, but cluster the servers so you don’t have to worry about where the data is. In fact, the last one I did I just left the old server up in the cluster as backup.
