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 ?

 

Ans :When you add offline device in cluster then it wont create an issue(your new device should not get in active active state by any mean)

 

4 "enable network fail-over" - is it mean release offline new_unit ? //we have configured network failover ( two units are conencted directly without switch)

 

Ans: That is after you reset or create new device trust validate configuration i.e network failover, config sync. and then perform any change on Online Active device. Perform Configuration sync to validate configurations.
