Removing a section in an if block while migrating to 2.0

Hello. I am trying to migrate my theme to 2.0. However, while deleting section tags, there is one section that is inside of an if block:

{%- if blog.template_suffix != ‘portfolio’ -%}
{%- section ‘article-heading’ -%}

..

{%- endif -%}

This piece of code is inside article.liquid and i need to know how i should replace this with a json file. Thanks!
