Windchill Webserver IP update and Domain update?

Hi everyone,

I'm going to be in the process of updating the internal IP,external IP(For Webserver), and Domain for our Windchill environment. I need to know the best method to go about this since this is all I'm changing.

How to make changes reflect IIS\APACHE so I can host on the internet?

How to make changes for other dependencies so I don't run into any major issues?

Thanks!
