Taking out a .html plugin

[SEODinosaur]

We are currently working on a new site structure and we would like to take out a WP plugin that adds a .html to the end of every URL.

From my understanding it is best to not use this plug in. Once I take out this plug in will I need to do anything for all the external links to count. Will the link juice pass through? if you type my url now without the .html in your browser it adds it in the .html. However, all the external links we built have the .html in the URL link.

Do I need to do any 301 or canonical to pass link juice or will I be fine after taking out the plug in?

After removing the plugin, you should configure a 301 redirect sitewide to strip out the .html and redirect to the version without the file extension. This way, both internal and external links won't lead to error pages, and you won't lose any link juice.

You'll also want to make sure your canonical tags are configured to link to the non .html version of each page, if they're hand coded.
