Enabling iCloud with Provisioning Profiles in my App

Question

I'm extremely new to iCloud development and while I have 2 versions of my app out in the app store, it's time to bring iCloud functionality.

There are a few questions that I need to ask. These may seem really basic, but I need to understand the right procedures before continuing and I can't seem to find this information anywhere online.

My app only supports iOS 7 and I'm using the latest Xcode as well.

Question and Uncertainty

All of the tutorials I've seen cover implementing iCloud into a new app rather than an app that already exists in the App Store and which already has an App ID and provisioning profiles. Do I have to create a new App ID or can I just edit my existing App ID to include iCloud and then generate new provisioning profiles?

Also, if I generate new provisioning profiles, will this directly impact any of my testing devices while I'm in the process of the iCloud development?

I'm sorry but I really don't know what to do here and any guidance on taking this forward would be really appreciated!

Thanks,

You don't have to create new app id simply what you have to do is add new features to existed app id.

If you go to apple development portal--> login to your account there you will see.

Click on Certificates,identifiers & profiles--> Click on Identifiers--> Then Click on identifier to whom you want to add new feature say "iCloud"

At the bottom you will see Edit button

Click on edit you would be taken to a new screen where you can add new feature iCloud to it.

Now here are few points that you have to remember.

You would have to alter you all certificates for this identifier and then regenerate new ones. Remember all provisioning profiles,certificates need to be regenerated for this App Id.

I have done so many times further you can ask i will help you.
