I have migrated my blog from WordPress to hexo, but the old URLs need to be permanently redirected.
I’m using NGINX as my web server, so I set up some rules for redirecting the old posts to the new URLs. It’s a bit tricky because WordPress used query string param for identifying the page, but it can be sorted out using
if and the NGINX
$arg_ variable. In order to generate these rules, I wrote a simple node script that runs through the exported Markdown files from WordPress. Markdown files were exported using Jekyll Exporter plugin.)
Then insert output from the script to the nginx server block of the old blog:
Now that all pages have been redirected 301 to their new paths, a simple comment export from WordPress and import to Disqus was automatically able to crawl the old URL 301 redirects and update the URL of the Disqus comments. (Using the crawl migration tool in Disqus admin.)
