In order to help you, we will need the following information for both your source (the current Dispatcher you have) and your target (the Dispatcher you aspire to have 😂😞
What OS are you on? Windows, Debian, RHEL, other?
What web server are you using? IIS, Apache HTTP Server?
What version of the server do you want?
What version of the Dispatcher module will you install?
I sent you a personal message as this issue is highly complex (as you can probably tell from the questions above). I'm performing a similar upgrade at the moment, perhaps we can collaborate to create some documentation?
My tips for a successful upgrade:
Regarding the upgrade of the server and the configuration of the server: Don't follow the Adobe documentation (sorry @Vish_dhaliwal😬) because it's no good. There are literally syntax mistakes in the configurations provided:
Prefer the README.md provided in the .zip of the Dispatcher download (almost right, it's just missing some crucial elements).
Once you've configured the server (IIS or Apache), you will have to configure the actual Dispatcher module (using .any files). A great resource for documenting this is weirdly difficult to find. You can get it here.
Hope this helps! Reach out to me via the private message if you'd like to get in contact 🙂
