Optionally, the subjects can be deleted, if they are not in another project, Project ID sequence numbers can be reset, and Randomization can be reset. Project IDs and Randomization only applies in projects where those features are turned on. This feature is used before placing a project into Production ModeData Collection Status.

From the Project Overview page, select Data Management in the toolbar
Select Bulk Data Tools in the left panel
In the Remove All Subjects section:
Check the box for Delete subjects from the system if they are enrolled in this project to delete the subjects in addition to removing them from the project. It is common to check this box prior to placing a project into Production ModeData Collection Status. If the subjects are being removed to clear the audit trail, then it is not necessary to delete the subjects as they can be re-enrolled into the project.
Check the box for Reset the sequence number used in generating ProjectId and RandomizationId to reset sequencing of Project IDs and Randomization IDs, in addition to resetting randomization if block sizes was used. Note that it is rare to uncheck this box.
