multiple sub domains under one MS tenant
Our company will be migrating our global O365s tenant with our global headquarter. We want to understand the potential impact of this migration.
Right now in our current tenant, we had to federate our parentcompany.com domain in order to get sub1.parentcompany.com sub domain to work with Okta federation. When we migrate to the new tenant that will include the follow domains:
Will all those other sub domain be automatically federated by Okta? The other sub domains such as sub1 and sub2 have ADFS or other MFA solutions.
Hi @9v3r9 (9v3r9) , Thank you for reaching out to the Okta Community!
The subdomains automatically inherit the authentication setting from the root domain, so you'll have to prepare for that. You might find more info on the Microsoft side if you need the subdomains to continue using your other solution.
The following articles seem to suggest that changes might be made after federation:

Hope it helps!
