Exchange full hybrid replace 2016 server with 2019
We are running an Exchange 2016 full hybrid set up with O365. We want to move to using an Exchange 2019 server for management and retire the 2016 server. Do we just install the 2019 server using the HCW in with a management license and then retire the 2016 server, or is there a different (better) process to use?

That's exactly how you do it.
Don't forget to:
- Migrate Certificates / create new Certificate
- Assign Certificate to SMTP / IIS
- Change Destination on your Reverse Proxy
- Change Destination on your Loadbalancer (if you have one)

- Thanks, I'll read through that. I love assistants, guides and checklists.

I had a question: when configuring Exchange hybrid on the new Exchange 2019, do you first have to move the external flow from 2016 to 2019?
Hello Andres-Bohren, can you please share some detailed explanations regarding activities that HCW performs on a new Exchange 2019 server? As far as I'm aware, HCW establishes a new connection to O365, and new connectors are created on-premises. Is that correct or there is something else that needs to be considered in the process of replacing Exchange 2016 Hybrid with Exchange 2019 Hybrid which is going to be used only for editing Exchange attributes?
- It does do some other stuff as well. High level process is outlined here: https://learn.microsoft.com/en-us/exchange/hybrid-configuration-wizard
- Thanks. I was hoping it was that straightforward, but with Microsoft and Exchange, you can never tell.
