Hello,

Best Case:
The OS admin updates the network configuration and that's all. SAP systems are not affecetd.

Worst case:
if the network driver has to be restarted then there could be some network outages. So users should accept risk and you should be prepared for system restart.

Regards,
Zav.

PS: only the netmask will be changed, Right? If IP addresses changes also then the SAP Systems should be restarted and some connected systems also.
