Only some spaces in a single instance of Confluence Cloud have updated UI/Editor...why?

[Daniel Reed]

We have a confluence cloud instance for our knowledge base. Some Spaces in that KB have the updated UI/editor (for example, the new blue styling for the "info" panel). Other spaces in the SAME instance do not.

Why isn't this rolled out for the whole instance? Or is there something I can do to get it rolled out to the whole instance?

Thank you in advance.

it has been brought to my attention that old pages will never use the "new UI/layout," only newly created ones. This seems to be what is going on, which I have to say, is somewhat annoying because the formatting on the old pages seems to have suffered some regression (no left padding on first column table cells for instance).

But I guess my original issue is a non-issue since I wasn't creating a new page (copying an old page to reuse much of the content). Any thoughts on an "upgrade page" feature at some point?
