Migrating to Dynamic Tag Management

Hi all,

I have a site tagged through on page JS, but would like to add new features / rules etc with the Dynamic Tag Manager.

I have created the web property, checked on the "Adobe Analytics page is already present" and rename the "Object Name" to s2.

But, for the s_code part, where either "managed" or "url" needs to be chosen I am not 100% sure what to do and what it involves:

I have read the manual: (https://microsite.omniture.com/t2/help/en_US/dtm/index.html#Adobe_Analytics)

but what should I do if I just wanted to add new features/rules but change nothing from the native code?

Many thanks,

Manuel
