[syslog-ng] Is there any problems when network config is changed?

I want to confirm the following point.
・ Syslog-ng server starts with two NICs(IPAddress A, IPAddress B), and it is configurated to received syslog-message with two IPAddress.
・ One client sends syslog-message to IPAddress A, and the other sends to IPAddress B.
I want to change network-config(IPAddress A → C) without stopping syslog-ng service and no influence to client which sends to IPAddress B.
