Signals Image Artist: Re-assigning dataset ownership

WARNING: Please ensure you have a valid backup before following the steps outlined below.

Use-case: A SImA user account is being deactivated and deleted, but the user's data needs to stay accessible to other group members.

SImA (v1.3 +) allows data ownership reassignment between user accounts via the change_owner Datastore API endpoint, accessible through the Swagger interface.

Workflow to reassign ownership:

1. Authenticate: Connect and authenticate against the Datastore API Swagger interface. Refer to the knowledge article: Signals Image Artist: Accessing the Datastore API Swagger interface

2. Navigate: Go to the PUT /change_owner/{old_owner_id}/{new_owner_id}endpoint, then click "Try it out".  

3. Execute: Enter the old_owner_id (current owner) and the new_owner_id (new owner), then click "Execute".

All datasets belonging to the old_owner_id will be reassigned to the new_owner_id. It may take a few moments for the changes to reflect in the SImA web interface.

Note: Result files, Analysis files, Assay Definition files, and other types of annotations will retain the old owner information. Their visibility/accessibility in the SImA web interface is defined by the parent resource (screen/plate/measurement) which should now use the new_owner_id.

Limitations: Selective reassignment of individual datasets is not currently supported. 

Identifying the owner ID:

The owner ID is found in the SImA web interface under the User Info table. Log in is as the SImA admin, select a user from the data tree, and the User Info table will display the "ID" (owner ID).
