Easiest way to change Group Slugs and Activity Slugs?

Hi there,

I am looking to change some slugs on my site that can't be changed by simply editing the titles.

Examples:

mysite.com/groups to mysite.com/networks

mysite.com/groups/my-old-group-name to mysite.com/networks/my-new-group-name

mysite.com/activity to mysite.com/news-stream (including all old posts to be display with news-stream slug and if there is a way to have Seo friendly slugs in activity items that'd be great too)

Thank you :slight_smile:
