Migration Notes: EDG 9.0 to 9.1
-------------------------------

Data Platform upgrade
^^^^^^^^^^^^^^^^^^^^^
Deployments that use :ref:`data_platform` must also :ref:`upgrade the Data Coordinator server <upgrading_data_platform>` to version 2.0.0-tq-4.

Deprecation of Microsoft 365 ROPC support
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
For Microsoft 365 integration features, TopQuadrant will drop support for *Resource Owner Password Credential* (ROPC) flow in an upcoming release, due to Microsoft's deprecation of this authentication method.
Customers using ROPC flow are strongly encouraged to transition to *Authorization Code* flow and/or *Client Credentials* flow, depending on the Microsoft 365 integration features used, as soon as possible.
See :ref:`Microsoft365AuthenticationConfigurationSection`.
