Hi,
I guess the initial plan is still solid, as you mentioned a SIC restart is not required however after performing a policy push from the new SMS with the updated management object using new IP address this is not of concern anymore? Or would a SIC reset still be required for the cert renewal?
If the IP Address of Security Management Server / Domain Management Server is changed, and SIC is never manually reset (between Security Gateway and Management Server), then the AutoRenewal of the Certificate will fail.
