jql7r (jql7r) asked a question.
We are currently using ADSync for Office 365, I've configured okta to match all accounts being synchronized and wanted to change over to Okta federation. Here are what I think my steps are below.
* Disable AD Sync
* Enable WS-Federation through Okta interface
Beyond those two steps, is there anything I'm missing? I don't want to lose any accounts or data as a results of my migration.
Thanks,

Hello Eric,
I would strongly recommend opening a Support Case with Okta regarding this concern. Office 365 is such a mission critical application which you do not want any downtime.

Office 365 integration FAQs
What should I do if I want to configure multiple Office 365 domains under one tenant?
You can use Automatic WS-Federation to configure multiple Office 365 domains in one app instance. See Federate multiple Office 365 domains in a single app instance.
However, if you are using Manual (PowerShell) WS-Federation, you need to configure a separate instance of the Office 365 application within Okta for each domain you have in your office tenant. For example, if you have five domains under your office tenant, you would have five office apps in Okta, each pointed to the same office tenant but set with a different domain. See Add Office 365 to Okta.
Can my users access Office 365 using POP and IMAP?
They can but we can't secure them through MFA since they don't use Modern Authentication.
We strongly recommend disabling these protocols in your Office 365 tenant. To disable these legacy protocols in your Office 365 tenant, refer to this Microsoft Support documentation: How to enable or disable POP3, IMAP, MAPI, Outlook Web app or Exchange ActiveSync for a mailbox in Office 365.
Why don’t I see options to license and roles while assigning the Office 365 app?
It’s probably because you haven’t set up Okta for provisioning users into Office 365. See Provision users to Office 365.
Can I use PowerShell to configure Office 365 in Okta?
Yes. See Configure Single Sign on using Secure Web Authentication.
