Hi,  I wanna know if there is any impact from changing the F5 self-signed device certificate to a CA-signed one - Is there any reboot? - any disruption connection will affect the LTM services? - ...

Hi Here_There,

there is a procedure for changing the BIG-IP system device certificate, that's the one for the WebUI:
K16951115: Changing the BIG-IP system device certificate using the Configuration utility
There is a different procedure for replacing the Device Trust Certificates. those are the certs used in a DSC / HA setup:
K47052252: Procedure to renew Device Trust Certificates on BIG-IP system
And lastly there is the default.crt in you find in System > Certificate Management > Traffic Certificate Management > SSL Certificate List. No need to change anything here.
