Answer 1

Make sure your environment is the supported coexistence scenarios for Exchange 2019:
https://learn.microsoft.com/en-us/exchange/plan-and-deploy/system-requirements?view=exchserver-2019
Exchange 2013 - Supported with Exchange 2013 Cumulative Update 21 (CU21) or later on all Exchange 2013 servers in the organization, including Edge Transport servers.

You need to update Exchange 2013 to CU21. Then install Exchange 2019 into your organization directly and re-run HCW to configure Exchange 2019 as a 'hybrid server'.
Don't forget to change related DNS records to Exchange 2019.

Same as if you have Exchange installed without hybrid.
https://assistants.microsoft.com/assistants/#/session/0bdd81d4-f507-4ee9-a4e2-8e8860f10663

Then when done, re-run the Hybrid Wizard and choose the 2019 server as the endpoint.

Ensure your firewall rules are updated as needed.

Install Exchange 2019 coexists with Exchange 2013 directly. After that, enable MRSProxy for your Exchange 2019 server:

Set-WebServicesVirtualDirectory -Identity "[<Server>\]EWS (Default Web Site)" -MRSProxyEnabled $true

After that, you will could rerun HCW to choose Exchange 2019 as hybrid server. If you want to uninstall Exchange 2013, you also need to configure virtual directory for Exchange 2019 and change public DNS(such as mail.domain.com, autodiscover.domain.com) record from Exchange 2013 to Exchange 2019.

Did you prepare the forest and install the pre-reqs? You have to do that.
Also, the error says the O/S is unsupported.

Update from Exchange 2013 CU 9 to Exchange 2013 CU 23 You need to update .net first:

You also need to install "Visual C++ Redistributable Package for Visual Studio 2013"

Try to run prepare command manually. Then try to run setup.exe again. If there still exist issue, provide the lasted version of error message to us.

Make sure the account that you used to install Exchange server contained in those group first:

Hi Kyle,

Good Day!

Just to give you an update, we recover the Exchange Server 2013 and it is successful. However, we encountered issue in migration of arbitration mailbox from Exchange Server 2013 to Exchange Server 2019.

Please see attached screenshot for the reference.

Hi Kyle,

Good Day!

When we transfer the Hybrid Setup from Exchange Server 2013 to Exchange Server 2019, do we need to remove first the setup in Exchange Server 2013 before running again the Hybrid Setup in Exchange Server 2019?

Or we can directly run the Hybrid Setup in Exchange Server 2019 without removing the existing configuration?

Thanks,
Raymond

You can run HCW directly and choose Exchange 2019 as hybrid server. If you want to uninstall Exchange 2013, make sure DNS record was changed to Exchange 2019 before uninstall Exchange 2013.

By the way, this thread mainly discuss about the general update process for Exchange. I would suggest you create a new thread to discuss about detailed issue which occurs during migration. Posts that are too long are not conducive to other users' read and reference.

Hello Raymond, I am in a similar process. I have a few concerns about the new installation of exchange 2019.
when you prepare AD, did you had to add the tentantorganization config switch?
