Stop the service. you can take the rows in application_server and application_server_model as is_deleted=1 for the _pxe instance.
OK, so to recap in more details, I would do this?
1. Stop PXE and TFTP services on the PXE server (and disable them)
2. Update application_server and application_server_model to set is_deleted field to 1 for the _pxe instance.
3. Restart each app servers (?)
Nothing else? No need to delete system packages (if any) or change any other blasadmin setting? What about infrastructure management, will deleting it that way remove it from the view too?
You don’t need to do #3.
