Conversion to 4.0

Hi Everyone,
I am currently setting plans to convert to 4.0. We have our local users as
well as a sister company that logs into their own database using Citrix and
Terminal Server. Vantage is installed on it's own server.
Could anyone help me out with some pointers on the conversion dealing with
the Citrix application?
You can reach me off the list as well; leave a message and I will call you
