I've got a site with over 500 articles on a subdomain (ex: blog.themoneysite.com). When it was set up years ago, it used a date+article title permalink structure. So articles look like blog.themoneysite.com/2016/12-buy-this-stuff-now These articles often point back to the main site, but only occasionally do I build links to the articles themselves, so losing linkjuice isn't a big deal. Aside from the pain of having to 301 each article, I'm wondering what effect changing the permalinks on the blog subdomain might have on the main site, if any? I'm in uncharted territory here lads, so I'd love to hear from people who have been down this path before.
