Our business is moving to a new O365 tenant in the coming months (aligning all child companies under a single parent company) and we are currently authentication users using Azure AD on our current tenant (specific to our company).
What implications / setup requirements will be needed by us to be able to authenticate users on our new tenant when this becomes available? Also how does it work with existing users, Tenant Admin, Ownerships etc.
We are due to have a test build of our new tenant next week, are we able to have multiple IdP's active at one time?
I'm not and IT person by any means so if this is going to be a problem then we need to know sooner rather than later so we can engage external support.
