What version were you upgrading from? The big NCM change in 7.3 is that NCM no longer has a separate database - NCM's data goes into the Orion database now.
If you are deleting the Orion.Nodes entry, you shouldn't need to also call RemoveNode - that should be taken care of automatically.
Other than that, things should pretty much work the way they did in previous versions. AddNodeToNCM is still needed when adding a node.
Hi Tim, sorry for the late Reply. I went ahead and "gave it a shot" and found that everything is working. We were upgrading from NCM 7.2.?
I still execute "RemoveNode" this does not give an error. I might go ahead and try to get rid of it and see how it works.
