Replace Exchange 2016 Server with Like

I need to replace a 2016 exchange server.

Build new 2016 server, install exchange 2016 on new server, move 2016 exchange instance to the new server then decommission old exchange.

Is there any documentation on how to accomplish this task, so far I have found none from Microsoft documents or anywhere else for that matter. Current exchange is not exposed directly to the internet; we have a proxy server with ARR installed. No one accesses email outside the organization except for selected mobile phone users and email is routed through a smarthost. I found this site but it lacks detail. Performing a Like for Like Exchange Server Migration (practical365.com)

Not sure how to accomplish this without disrupting current mail flow. I am not an exchange expert so I would need detailed steps. If anyone can help by pointing me to a site or Microsoft instructions I would appreciate your help.

Thank you,

Mark
