Reset a Sandbox (SIG or ODS) Instance in Control Center
If you have sufficient permissions, you can use Reset to reset an instance, resetting the instance to a clean state. Resetting deletes all data from the database. You can reset SIG sandbox and on-demand sandbox (ODS) instances, but you can't reset PIG instances (production, staging, and development instances). This limitation prevents the accidental deletion of mission-critical data.
To reset a SIG sandbox or ODS instance, perform the following steps:
Control Center resets the instance and sends an email with the new password to the email address of the Control Center account that ran reset. The user must start the instance in Control Center, wait until the system is up, and then log into the instance with the new password. The user is prompted to change passwords when they log in with the new temporary password.
