I already mentioned it on the discord, but I'll say that again here, just so people here might see it:

Now that I think about it, any deleted WN content can be restored via the "history" that keeps former versions archived. So it should be no problem with, for now, just replacing the WN stuff by LN stuff. But out of consideration for the amount of info that might just "disappear" all of a sudden, I'll start will smaller pages first.

To make it easier in the future to find the "cut-off points" where it was changed to purely LN canon, I'll mark any such edits I'll do with the comment "Conversion to LN." in the history. That way if later a WN version is made, you can find the content for that in the history more easily, though it should be noted that currently, many pages are already mish-mashes of WN and LN content, so making seperate WN versions is going to be lots of work one way or another.
