Hi Roger,

Yes you can copy the critical node configuration into the spare node's. 

However, it really does depend on what that critical node does and any special 
requirements it has. It may have services that might need to be managed across 
one by one. Or it may require one node to be shutdown before the other come up. 

Anyway, short answer is yes, you can copy the node definitions if that makes 
sense to do so.
