I'm looking to update my Exchange Hybrid servers from CU13 to CU22 with the latest security patches.
First I'll give the environment so the you can better understand the problem. I have two Hybrid Exchange servers in different sites (Site1 and Site2) but the same domain / forest (domain.lcl). These Exchange servers both connect to our O365 Tenant. There are DCs in both sites.
Site 1 - has a Exchange Server and 3 DC's . The schema is in this site. Servers are all 2016 DataCentre.
Site 2 - has a Exchange Server and 1 DC. Servers are all 2016 DataCentre.
I intended to install the prereqs - .Net 4.8 and IIS URL Rewrite.
I'm attempting to update the exchange server at Site 2 first as a test. This is what I have used so far to not avail.
- setup.exe /PrepareSchema /IAcceptExchangeServerLicenseTerms_DiagnosticDataON
- setup.exe /m:upgrade /IAcceptExchangeServerLicenseTerms_DiagnosticDataON
These fail for a number of reasons.
- [ERROR] Setup encountered a problem while validating the state of Active Directory: Exchange organization-level objects have not been created, and setup cannot create them because the local computer is not in the same domain and site as the schema master. Run setup with the /prepareAD parameter on a computer in the domain domain.lcl and site Site 1, and wait for replication to complete. See the Exchange setup log for more information on this error.
How can I get the Schema updated in the current environment? Can I update the Schema directly using the files that the setup copies?
Any help would be greatly appreciated.
