Splitting company into 2 tenants

Hey PaulSmith2250,

While you certainly can sync from one AD domain to different tenants, you will have to plan out for example which OU syncs to which tenant via a different ADconnect server, here is the official documentation from Microsoft:

https://docs.microsoft.com/en-us/azure/active-directory/hybrid/plan-connect-topologies#each-object-only-once-in-an-azure-ad-tenant

That being said, There is more to consider here, like one domain can only be added into one tenant at a time and how you would be migrating data out of source to destination tenant.

Thanks
