At Migrate Exchange Server 2007 from SBS 2008 to a new Exchange Server 2013 on Windows Server 2012 R2
The Command Line reads: setup.exe /mode:install /roles:mb,ht,ca /<and other stuff>
But the Release Notes on Exchange 2013 CU23 now state that /PrepareAD should be manually executed as part of the installation.
Also, does the HT switch in your command line stand for Hub Transport and if so, is that valid for a 2013 install (where that function is now contained within the CAS and MB Roles)?
Thank you
On a new installation /PrepareAD is not needed, when you upgrade an existing installation it is. Setup still responds correctly to 'setup.exe /mode:install /roles:mb,ht,ca' but you are correct that the modern way of doing it can be without 'HT'.
I have not yet used CU23 in a 2007 migration. With CU22 everything worked as in the guide is shown. I would be very surprised if it is any different from CU23. Setup will run PrepareAD even if you do not declare it, see Step 5 screenshot. If that does not work for you run the setup with /PrepareAD.
