After upgrading to a 9.0 version of DNN (9.0.1, 9.0.2, etc.,) customers may notice that the Import/Export option is missing from Persona Bar > Settings.
This is intended functionality, as the feature was removed in 9.0 versions. However, due to customer demand, Import/Export was added back in version 9.1.
We highly suggest upgrading to 9.1+ in order to gain back Import/Export functionality. Should you run into any issues during the upgrade process or have any questions, please open a ticket with us from this portal.
