helloRicardoGDR ,

 

We are about doing exactly the same, the only difference is we have installed exchange 2019 CU13.

 

Installing exchange 2019 doesn't Brake anything from your exchange 2013 config. We have already installed two 2019s and everything continues to work.

 

We have moved two mailboxes to the 2019s and the only thing is not working is outlook anywhere. I believe outlook anywhere is still pointing to the old 2013s . Apart from that I can access my Mailbox ( I moved mine to 2019) send and receive mails is fine.

 

Regards!
