Prepping exchange for upgrade from cu19 to CU22... if i run the setup.exe /PrepareSchema /(licensestuffblahblah) in cmd, it gives me the error that the schema is not ready and fails, same as the wizard. I don't need to run the /PrepareSchema command if exchange is already installed, do I? Should i go directly to the /PrepareAD command? And on a single domain, i don't need to run the /PrepareDomain command do i? I'm getting mixed signals from the documentation.
If you run "Alternately, you can run setup.exe /PrepareAD
on a domain controller."
Does it work? that error indicates trouble contacting the FSMO Schema Master DC.
You mean run Setup.exe /PrepareAD at the exchange cmd prompt? How do i run it on a DC? Mount the iso on the DC?
If this a single AD forest domain, then you can run setup from the GUI and it will do all the steps for you - assuming you have the correct perms:
https://learn.microsoft.com/en-us/exchange/plan-and-deploy/prepare-ad-and-domains?view=exchserver-2019
However, if its failing, it wont matter and it wont run of course
What is the exact error?
Here's the command... run on exchange 2016 CU19 on server 2016... the DC it's checking against is a 2012R2 with a functional level of 2008r2.

The Active Directory schema isn't up-to-date and the Active Directory management tools aren't installed on this
computer. To install the tools, install the 'RSAT-ADDS' Windows feature. Alternately, you can run setup.exe /PrepareAD
on a domain controller.

The Windows component RSAT-ADDS-Tools isn't installed on this computer and needs to be installed before Exchange Setup
can begin.

The Exchange Server setup operation didn't complete. More details can be found in ExchangeSetup.log located in the
<SystemDrive>:\ExchangeSetupLogs folder.
Correct. If you dont have .net 4.8 installed on the DC however it will prob fail the pre reqs.
If so, and you dont want to install .net on the DC, then you will need to figure out what the Exchange Server cant contact the Schema Master DC. If this is a single domain forest, then it should have no issues doing that
mount the iso on the DC, run setup.exe /PrepareAD and see what happens?
Why not? :)
Hi @jeff mcnabney ,
Please also check the required components:
https://learn.microsoft.com/en-us/exchange/plan-and-deploy/prerequisites?view=exchserver-2016#windows-server-2016-prerequisites-for-exchange-2016
