I have one on-prem Exchange 2010 Hybrid server and a couple Hub Transport servers, and a Mailbox server. I'm trying to install an Exchange 2016 server so I can migrate off 2010.I'm running:
Setup.exe /PrepareAD /TenantOrganizationConfig d:\exchangeserver2016-cu23\MyTenantOrganizationConfig.xml /IAcceptExchangeServerLicenseTerms_DiagnosticDataON
I get:
A hybrid deployment with Office 365 has been detected. Please ensure that you are running setup with the /TenantOrganizationConfig switch. To use the TenantOrganizationConfig switch you must first connect to your Exchange Online tenant via PowerShell and execute the following command: "Get-OrganizationConfig | Export-Clixml -Path MyTenantOrganizationConfig.XML". Once the XML file has been generated, run setup with the TenantOrganizationConfig switch as follows "/TenantOrganizationConfig MyTenantOrganizationConfig.XML". If you continue to see this this message then it indicates that either the XML file specified is corrupt, or you are attempting to upgrade your on-premises Exchange installation to a build that isn't compatible with the Exchange version of your Office 365 tenant. Your Office 365 tenant must be upgraded to a compatible version of Exchange before upgrading your on-premises Exchange installation.
I've exported the xml file 2 times, so it isn't corrupt. I've never seen anything about upgrading a O365 tenant.
How can I find the problem?
