As you would have noticed in not only Exchange 2019 but 2016 that when you type a certain command you will receive a nice yellow warning to use the new cmdlet instead.
For example, I ran the following command:
- Get-TransportServer
And as you can see below, the warning:
![Exchange 2019:- how do i open the exchange management shell on windows server 2019 core? Exchange 2019:- how do i open the exchange management shell on windows server 2019 core?](https://everything-powershell.com/wp-content/uploads/2019/11/image.png)
when you run the new cmdlet that they advise you to use, you will still get the desired result, but with no warning, the command run is as follows:
- Get-TransportService
![Exchange 2019:- how do i open the exchange management shell on windows server 2019 core? Exchange 2019:- how do i open the exchange management shell on windows server 2019 core?](https://everything-powershell.com/wp-content/uploads/2019/11/image-1.png)
This is just one of many changes but be aware of them and try and use them vs using the old cmdlets.
Hope it helps.
