Thanks,
I implemented the redirection myself, I also wanted to make sure that all the old urls would work, so I modified the theme of the old website to redirect each page (I had the same relative url on the old and the new website):
<meta http-equiv="refresh" content="0; URL=https://zonca.dev/{{ article.url }}">
<link rel="canonical" href="https://zonca.dev/{{ article.url }}">
This is for Pelican, but something with a similar syntax should work on Jekyll as well.
