SOLUTION:
Thank you! I found the suggested SharePoint Designer solution above to work beautifully!
Here are the steps that I took:
- Follow the instructions above by opening the List in SharePoint Designer, selecting All Files under the navigation node (near the bottom)
- A bunch of folders appeared - I selected the folder named 'Lists'.
- From here, it will show the list names and the display names. Change the actual name of the list (first column) by right-clicking on it, rename. This will update the url. You may wish to match this to your display name.
- When you return to your site, the navigation link for the list may still go to the old URL. To update this, enter in the new url in your browser, go to List Settings > Title, Description and Navigation. Simply hit the save button without making any changes. The navigation link is now updated.
Please note: If you are updating list urls and names of a project site (from Project Server), do not rename the Risks, Issues lists. These must remain for Project Server to function properly.
