   5. Click the run button (>>)

Additional Information:
  • The data collector must not have any devices on it to perform the above procedure.  So existing devices will need to be either deleted or moved to another collector using the "rebalance" functionality
  • <DA_HOST_IP> in the above URL represents the Data Aggregator (either hostname or IP address).
  • The content type must be set to application/xml; charset=UTF-8 with the REST client before the above procedure can be performed
