Yes. The project owner or project lead roles can be changed and updated at any time. Only the record owner or UQ lead has the authority to make this change. In fact, should either leave UQ they must update the project record to include a new UQRDM project lead or owner. See how to change the record owner or UQ lead.
First ensure that both your student account and staff accounts are listed on the project record. If not you will need to add your student account as a new collaborator on your project, and activate that account.
You can then make your student account the project record Owner by clicking the three vertical dots and selecting "Make Owner". See how to change the record owner or UQ lead.
You can delete a UQRDM project record where no storage has been provisioned. Usually this means the record is incomplete, or has not been approved (pending approval) by the UQ Lead.
The record will be removed from UQRDM, and will not be found in either your R:/ drive or via the cloud interface.
If you wish to remove an active record with data stored, take the following steps.
