Exchange 2019: Don't forget the cmdlets are changing.
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:
WARNING: The Get-TransportServer cmdlet will be removed in a future version of Exchange. Use the Get-TransportService cmdlet instead. If you have any scripts that use the Get-TransportServer cmdlet, update them to use the Get-TransportService cmdlet. For more information, see http://go.microsoft.com/fwlink/p?LinkId=254711
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
This is just one of many changes but be aware of them and try and use them vs using the old cmdlets.
