Wordpress Migration Story: Link Preservation/Emulation
One of the issues that came-up in my migration to WordPress is the change in permalinks. The permalink system is different from that of Blogger, and the change caused all the existing links from Google Search to fail. Since most of my hits come from organic search results (like that of Google and Yahoo),I’m gonna have a few days of nothing until the search engines get updated with my new structure.
Fortunately, WordPress supports customization of the permalink structure. I had to setup WordPress with the same style of permalinks from Blogger (<url>/yyyy/mm/<post name>.html), which allowed some of my simpler posts to easily stay intact.
This is not enough, though. WordPress and Blogger’s post name to URI conversion system also uses different algorithms, some of your posts might have different permalink URIs. Fortunately, you can control this to a certain degree by editing the “Post Slug” of each individual post to match that of the original name. I’m pretty sure WordPress can do this automatically during import, but I guess it’s not a high priority feature for now. Regardless, WordPress allowed me to do so manually.
Given this flexibility, I was able to revert my posts which generates the most number of hits to match that of the current Google results. The Google results from the tags/categories and archives still don’t work (and those are probably tougher to emulate), but at least I was able to preserve some of the pages.
