SharePoint 2013 File Not Found Missing Page Layout

Question

How do I detach a page layout from a page and attach a different one? Is there a powershell command. SharePoint Designer is throwing an error.

I deployed a new set of master pages and page layouts and removed my old ones. I missed detaching a couple pages from the page layouts and now when I try to open those pages I'm getting a File Not Found. I've recovered the old page layouts and I still cannot open the pages. I tried detaching the page layout in SharePoint Designer but it's throwing an error "operation is not valid due to the state of the object."

I found the solution: I had to download the page and edit the properties in a text editor and then upload the file. DO NOT DELETE THE FILE on the SharePoint site and re-add. It but be copied over the original.

Steps to fix this issue. Download the SharePoint Page. Navigate to the location of the new page layout Take note of the following: 1) Name 2) Title 3) ContentTypeId (IN THE URL).

Edit the Page in text editor - use the values from above without the " *" below. Replace xxx.xxx.com with your site. |mso:ContentTypeId msdt:dt="string"|***ContentTypeId* |/mso:ContentTypeId| |mso:PublishingPageLayoutName msdt:dt="string"| Name |/mso:PublishingPageLayoutName| |mso:PublishingPageLayout msdt:dt="string"| https://xxx.xxx.com/_catalogs/masterpage/ Name , Title |/mso:PublishingPageLayout| Upload the Page to the same location as the original.
