Is there any official doc which says,"AA can be implemented on any site developed using any CMS?" Specific case- a site is developed using SiteCore CMS and client wants to have AA implemented. I am sure that AA is compatible with SiteCore but official confirmation wl b helpful too
It is not about CMS, any website which includes scripts required by Adobe Analytics to capture user behavior, can implement Adobe Analytics. 3 ways you can implement Adobe Analyitcs in your Sitecore CMS based website.
This guide walks you through different Adobe Analytics implementation methods.
Adobe suggest and prefers implementation using Adobe Experience Platform Launch as they are phasing out Dynamic Tag Management in near future
Hope this helps
