The awkward part of this migration is not the new portal. It is the overlap.
Microsoft is moving Android-based Teams Rooms, Teams phones, Teams Panels, and SIP devices out of Teams Admin Center and into the Teams Rooms Pro Management Portal. Update management is moving with them, and Microsoft says the new portal will become the primary management location.
That sounds tidy until you remember that Microsoft is still running both paths during the transition. Update phases in Teams Admin Center are being mapped into update rings in the Pro Management Portal, and some settings already live only in the new portal. In other words: two admin surfaces can describe one fleet, but not always with the same timing or policy view.
The operational risk is simple to miss. An admin can provision a device in one place, then investigate updates in the other, and conclude the policy failed when the device is actually sitting in a different stage of the migration map. That creates unnecessary support noise and bad handoffs between workplace IT and AV teams.
The useful rule is to assign one source of truth per lifecycle step. Provisioning, update control, and ongoing monitoring should be checked against the same portal during the transition, even if both tools still work. If you split those checks, you will spend time debugging the migration instead of managing the fleet.
Consolidation only reduces friction when the operating model follows the control plane.
