Clarify for me cross-channel tracking

Code replaces existing code you may have within page or is additional code?

Can anyone clarify for me? Does the cross-channel tracking code that google generates for you, does the code replace the existing code you may have within the page, or is this additional code. Replace or additional?

On the landing pages, it's additional code.
On the conversion pages, it's uses the traditional tracking code.

Thanks.

Is it possible to put more than one additional landing code on landing page (I have different campaigns which have the same landing page)?

Yes. You can put more than one conversion code on a single page.
