On this URL https://portal.liferay.dev/docs/7-1/user/-/knowledge_base/u/forms, there is a section that reads:
Kaleo Forms: If you're a Liferay Digital Enterprise customer, there's a third form building tool called Kaleo Forms. It integrates form building with workflow to create form-based business processes, like a Conference Room Checkout Form, or a Support Ticket Process so support tickets go through the proper channels on their way to resolution. Read more about Kaleo Forms in the workflow section.
There are two links that point to the old Customer Portal, https://customer.liferay.com. When you click them, they don't redirect to the proper Help Center URL - which I believe should be https://help.liferay.com/hc/en-us/articles/360018174191-Kaleo-Forms. Instead, it redirects to the Help Center home page.
Please update the old Customer Portal links to the current Help Center pages.
