In Vinson, backend allows you to migrate CMS content, but when using the SMT records are still created in the old version 2. The configuration does not offer the option for SMT 3. Is it possible to use SMT 3 with Vinson? Is there a patch? Suite Answers reveals that Kilimanjaro by default uses SMT3 .

Kilimanjaro or newer 🙂 https://developers.suitecommerce.com/suitecommerce-advanced-feature-compatibility-matrix.html

Thats what I thought but hoped I was wrong ;>( Is there a way to remove all the cms contents in bulk when we did the cms migration? I feel like they cause confusion.

I don't know about whether it is possible, sorry
