Exchange Hybrid Prepare AD

Question

Hi All

I am using Exchange 2016 hybrid environment. I am using Exchange Server 2016 CU21 Jul21SU. I want to upgrade it to Exchange Server 2016 CU22 Jan22SU.
I can see that schema upgrade is required. which of the below syntaxes should i run. Do i need to export TenantOrganizationConfig file from exchange online and import it.

  Setup.exe /PrepareAD /IAcceptExchangeServerLicenseTerms_DiagnosticDataON 
    Setup.exe /PrepareDomain /IAcceptExchangeServerLicenseTerms_DiagnosticDataON

    or

    Get-OrganizationConfig | Export-Clixml -Path "C:\MyTenantOrganizationConfig.XML" (Export this file from exchange online)
    Setup.exe /PrepareAD /TenantOrganizationConfig MyTenantOrganizationConfig.xml /IAcceptExchangeServerLicenseTerms
    Setup.exe /PrepareDomain /TenantOrganizationConfig MyTenantOrganizationConfig.xml /IAcceptExchangeServerLicenseTerms

Answer 1

Setup.exe /PrepareAD /IAcceptExchangeServerLicenseTerms_DiagnosticDataON   
Setup.exe /PrepareDomain /IAcceptExchangeServerLicenseTerms_DiagnosticDataON  

You will be good running those first two commands since you already have Exchange installed.
