Use the Upload Certificates option to upload server certificates for network engines independently from other actions. This method is much faster than if you were to upload the full database with the Upload To Device option under Manage Archive.
When you upload a certificate from a network engine, SCT associates the engine's certificate with the engine in the archive. Any previously existing certificates remain in the archive, but are no longer associated to the network engine that you uploaded. If the certificates are the same, no changes are made to the SCT certificates for the engine.
