best practice to upgrade citrix web interface 4.6 to 5.0
I have production Citrix secure gateway server configured in DMZ zone to allow external users to login via Citrix Web Access.
I am planning to upgrade just the WI component from 4.6 TO 5.0 in production Citrix Secure Gateway server. I would like to know what is the best practice?
When I run WI 5.0, will it retain the configuration? OR will I have to configure all the site settings?
