    Hi Mirza Dedic,

     

    You can run the Wizard in the stage that you want, you will need is to point all services, iis, and autodiscover, receive connectors, send connectos and so on to the new Exchange 2019 to the clients connect to them.

     

    Then if you are going to migrate all mailboxes to 2019 and some of your mailboxes to 365 you can run wizard and only select the Exchange 2019 infrastructure, then migrate all that you need. After this you only will need to uninstall 2013.

     

    If you are upgrading an Exchange infrastructure, is advised to point all services to the newest Exchange to avoid issues.

    Hi Nuno, NunoAriasSilva 

     

    That makes sense and was my plan. What I was a bit confused about is during the hybrid configuration wizard's send connector page, it did not allow me to select Exchange 2013, only Exchange 2019 servers yet on the receive connector page it showed all 3. This threw me off and I did not apply the latest HWC settings.

      Hi Mirza Dedic, 

       

      Yes as the best practice is to point all services to the newest Exchange servers the Wizard does not show the previous Exchange. Change it and apply the latest HWC settings, and post here the ongoing results.

        I pointed all services to new Exchange 2019 servers and re-ran HWC, no issues so far. In process of migrating TBs of data.
