modify CGNAT pool will cause dropping of connections?

Hi

 

I have a question regarding CGNAT pools and the question is what will be happened if i modify the pool of a CGNAT Virtual Server? for example extending the current subnet or reduce the scope range will cause to dropping of existing connections? It's obvious that reducing the scope will cause to drop the connections that matched the source addresses which was removed from the pool but does the system drop the connections even the pool changed in any other way?

 

Thanks
