Hi there
Yes, I would consider this a priority as you want to have the most upto date and relevant markup on your site, so that crawlers can better understand your important information and attribute the right properties to your site/content.
I would also focus on Schema, as it's recognized by major search engines like Google, Bing, Yahoo, and Yandex, so you are pleasing multiple crawlers at once. Pages that have this markup also tend to rank four positions higher than pages without. So it is definitely worth the investment of time.
Hope this helps! Good luck!
