Exchange upgrade issue

Question

Hi,

We're trying to update our exchange hybrid deployment to exchange server 2019 and I've encountered somewhat of a roadblock. When I run the pre-requisite checks it throws up an error that we need to update our 2 Exchange 2013 CU 13 servers to CU 21 and I've encountered this error:

Error:

The following error was generated when "$error.Clear();

      if (Get-Service MpsSvc* | ?{$_.Name -eq 'MpsSvc'})

      {

        Set-Service MpsSvc -StartupType Automatic

        Start-SetupService -ServiceName MpsSvc

      }

    " was run: "Microsoft.PowerShell.Commands.ServiceCommandException: Service 'Windows Defender Firewall (MpsSvc)' cannot be configured due to the following error: Access is denied ---> System.ComponentModel.Win32Exception: Access is denied

--- End of inner exception stack trace ---".

From googling around it seems that it's referring to some sort of incompatibility. The 2 exchange servers we currently have are running Windows Server 2012 R2 and Windows Server 2019. Is it actually the case where I can't update this version of exchange and I need to go through the process of just installing Exchange Server 2019 on a fresh environment?

Thanks in advance,

Dan

Install Exchange 2013 on Windows Server 2019 isn't supported, so try to migrate mailbox to the Exchange server, then uninstall the unsupported Exchange server :

Exchange 2013 CU 21 doesn't supported download now, I would suggest you try to update it Exchange CU 23 directly.

Please make sure login computer with domain admin account and install Exchange with administrator rights. Before update Exchange from CU 13 to CU 23, you need to install Visual C++ Redistributable Package for Visual Studio 2013 and .NET Framework 4.7.2 first.

Windows 2019 is the mandatory System requirement for Exchange 2019. So, it is not possible to upgrade the version until you have all exchange servers are running Windows 2019
