TenantOrganizationConfig parameter when upgrading from Exchange 2010 to 2016 in a hybrid Ex2010 / M365 environment

I want to upgrade my test environment from Exchange 2010 to 2016, using the parameter: /TenantOrganizationConfig
What exactly does this do to my M365/Azure AD tenant?
Can I still use Exchange 2010 in my live environment after the /TenantOrganizationConfig paramter is used?
If I do this successfully in my test environment, can I do the same command in live environment again, or will it fail?
Thanks
Richard.

Welcome to Microsoft Exchange Server 2016 Unattended Setup
Copying Files...
File copy complete.
Setup will now collect additional information needed for installation......
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".So no then.

What exactly does this do to my M365/Azure AD tenant?
When we configure the hybrid, information is stored in AD, at present, we migrate exchange 2010 to exchange 2016 and update the AD, we should use /TenantOrganizationConfig to update Tenant configuration information.
Can I still use Exchange 2010 in my live environment after the /TenantOrganizationConfig paramter is used?
Exchange 2010 is end of support, we suggest you use exchange 2016 hybrid.
If I do this successfully in my test environment, can I do the same command in live environment again, or will it fail?
It looks seem no problem, in case you'd better do backup.
In addition, here a guidance on Hybrid Exchange 2010 To Hybrid Exchange 2016 for your reference and hope it help.

Yes, I am busy migrating to Exchange 2016 (then 2019) but I want to make sure I can still use 2010 whilst the migration takes place.
How do you do a backup of your tenant?!? I never heard of that!Regards

2022-10-07T07:24:31.37+00:00 Hi @R Artes ,
I have done some research, and you can still use exchange 2010, there is no impact on mail flow, here's a similar thread on the issue for your reference: 2010 -> 2016 hybrid migration: Mail flow impact
Please Note: Since the web site is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.How do you do a backup of your tenant?!?
Yes, there seems no function which can back up the Microsoft 365 tenant configuration, and I mean that you could backup AD, for more details: Back up and restore Active Directory domain controllers
In addition, here a guidance on Hybrid Exchange 2010 To Hybrid Exchange 2016 for your reference and hope it help.
