We will change the CSS's to ACE's plataform's.
Do u know any aplication wich can convert the basic CSS configuration into ACE configuration?
The certificates installed in the CSS could be migratted to the ACE ?
The 4710 with the ACE software has a built-in CSS-to-ACE conversion tool accessible through the web interface. See http://www.cisco.com/en/US/docs/app_ntwk_services/data_center_app_services/ace_appliances/vA1_7_/configuration/css_to_ace/user/guide/cssaceug.html for example.
The tool may not convert 100% but it may provide a good starting point.
I don't see any reason why you can't export the certificates from the CSS (assuming you remember the password) and import them into the ACE.
