## Symptoms

- * SmartEndpoint cannot access Endpoint Security Server after Advanced Upgrade.  

* The Migrate Export from the old server and the Migrate Import to the new server are finished successfully.  

* When trying to connect with SmartEndpoint console to the new server, a message is displayed that the server is not running.  

* In *server_messages.log* , see:  

  INFO Dispatcher-Thread-9 - Certificate subject name: CN=cp_mgmt,O=AAAAAAAAA  
  INFO Dispatcher-Thread-9 - SIC name in registry: cn=cp_mgmt,o=BBBBBBBBB  
  FATAL Dispatcher-Thread-9 - Server failed to start. Shutting down..   
  com.checkpoint.uepm.api.epsbackend.is.EpsBackendException:   
  TICKET_NUMBER = XXXXXXXXX.   
  Certificate subject name "CN=cp_mgmt, O=AAAAAAAAA" does not match SIC name stored in registry "CN=cp_mgmt, O=BBBBBBBBB".

## Cause

The Hostname of the new server is different from the Hostname from which the Migrate Export was taken from.

Due to the Hostname change, the certificate on the new server doesn't match the certificate imported from the old server.
