Update AD schema to Exchange 2019
Hi.
I currently have an Active Directory forest at functional level 2012 R2 which has integrated Exchange Server 2013 CU8.
What I want to know is, if I want to install Exchange Server 2019, I must first uninstall from the Active Directory Exchange 2013 schema? Or does the Exchange Server 2019 installer update the schema?
Thank you very much for the help.
Best regards
The requirements for the network and the directory servers in your Exchange 2019 organization are described in the following table:
Component Requirement
Domain controllers All domain controllers in the forest need to be running one of the following versions of Windows Server:
Windows Server 20221 Standard or Datacenter
Windows Server 2019 Standard or Datacenter
Windows Server 2016 Standard or Datacenter
Windows Server 2012 R2 Standard or Datacenterthis command is used when performing the pre requisities for installing exchange 2019. So the setup will indeed update the schema.
Setup.exe /PrepareSchema /IAcceptExchangeServerLicenseTerms

Yes its recommended to update the schema and update the .NET before installing the CU . When you run the CU it will check for all prerequisites in case your schema or your .net are not updates it will tell you to update them prior proceeding
