Thank you for your answer. I have few questions regarding last steps you talked about. I put below only steps which aren't done yet or aren't clear to me.

 

1 "Make this new device forced offline" - it's clear 2 "no-shut/Connect Ethernet ports on switch level" - it's clear 3 "After that you can make new device trust" - can it be done without any service disruptive? (if there would be service disruptive i have to get permission for service window from business) - would it be "enough" to reset trust ? 4 "enable network fail-over" - is it mean release offline new_unit ? //we have configured network failover ( two units are conencted directly without switch) 5 config sync - it's clear

 

Regards Tom
