How do I make my new Exchange 2019 server the primary Exchange Server?
I admit to being caught with my pants down when it came to using Windows Server 2012 R2 and Exchange Server 2013 becoming obsolete. I run my own servers on-premises. I have now built a new server ...
- I had to surgically remove the old Exchange 2013 server from my domain'
s Active Directory.
In my opinion removing existing Exchange server Add/Remove Programs very last step.
Before it Michael Faklis should migrate existing mailboxes to new server.
So I propose extend your procedure as below:
2a. Create new mailbox databases on Exchange 2019.
2b. Move existing mailboxes as described https://theitbros.com/move-exchange-mailboxes-to-another-database/ (targets will be databases from step 2a.).
2c. Move any customization made on Exchange 2013 to Exchange 2019.
2d. Recreate receive connectors configuration on new exchange (receive connectors' configuration is individually per server as opposite to send connectors).
2e. Move TLS certs (or create new if needed) to Exchange 2019.
3. Then. Remove the existing server through Add/Remove Programs.
The replies so far are not adequate for my needs. I'll post what works when it actually works. Thank you to everyone who participated.

The above replies are correct but may not be complete for your scenario
