When deleting CAs take into account that:
- Before deleting a root CA, you must delete all issuing CAs under the root CA.
 - Before deleting an issuing CA, you must first remove any CA Gateway Credential and Enrollment Gateway associated with this CA.
 - When you delete an issuing CA, you also delete all the certificates you issued from this CA.
 - After deleting a CA, the CA license returns to inventory, generally within 24 hours.
 
CA deletion is not reversible.
To delete a CA
- Log into cloud.entrust.net
 - Navigate to Administration > PKIaaS Management.
 - Select the row of the CA you want to delete and select Actions > Remove.
 - Review the information on the confirmation request before confirming the deletion.
 - In the CA grid view, the CA status becomes Deleting while the deletion is processed (usually ~60 seconds).
Refresh the grid. You will notice that the deleted CA is no longer listed.
