推荐一个修改永久链接的插件

我一直想修改自己的永久链接，始终认为现在的不太合理，因为我需要我的连接是这样的格式http://xxx.com/html/cat/name_art_id.htm，因为这样看起来好像所有的文件都在html下面，方便今后全部静态化，但是如果你擅自将url修改了，可能会导致搜索引擎抓取404错误，这样对站点的访问影响是非常大的，所以我一直不敢做这件事情，现在好了，发现了这样的一个wp plugin permalinks-migration，有需要的可以下载下来一用

With this plugin, you can safely change your permalink structure without breaking the old links to your website,and even doesn’t affect your search engine rankings.

introduction

Many people want to change their permalink structure,for example, from /%year%/%monthnum%/%day%/%postname%/ to /%category%/%postname%/

But doing so will make all pages indexed by search engines become invalid,moreover, losing visitors from other sites or bookmarks that links to you.
