Hello, I am having CUCM 8.6 on MCS with IP address x.x.x.x and I will migrate and build a new CUCM 11.5 on UCS 

I want to install new one offline with the same IP address x.x.x.x then switch network cables to go live

My question is I want the new one record on the DNS server on the initial network although it isn't reachable

Is CUCM installation check DNS reachability

What Shall I do with that scenario ?

CUCM install checks NTP and DNS, DNS failure can be ignored, but NTP cannot, so in order to install the CUCM you will at least need to stage an NTP server.
