Netlify has their own way of doing redirects. I’d drop all the
aliases in front matter, and instead create
_redirects for all your old URLs. You can probably figure it out with a single rule and
:splat to construct yer redirect.
Or, ya know, don’t worry about it. You only got like 70 pieces of content. It will get reindexed quickly, and you can put a mention on the 404 about it or something.
I would do anything aside from using
aliases for your specific case, because it doubles the amount of content files you’ve got, and I don’t know, that just annoys me. Let’s keep those files down!
You can search the forums, there are a bunch of Netlify and alias conversations. Let me know how it goes.
