Unfortunately, I've made pages with capital letters in the URL and I want to change them. As the question asks there a way to change the URL name without moving the page?
Or is there a way to change multiple URLs at once?
Try running groovy scripts on the AEM project, it's easy to setup and easy to execute. I have implement something similar where I had to update the title of the page. Let me know if you need any help in creating groovy scripts for the mentioned automation. You can also refer Groovy Scripts on AEM Content
