Our SP2013 farm contain 10 site collections. Each collection have their own Master page. In one of site collection I created a page with some OOB search webparts and a customized natvigation webpart. The natvigation webpart is shared with all 10 site collections.
I have tried open two SC with Sharepoint Designer 2013 and copy & paste over this page. The page load up an error "Sorry, something went wrong This page is not using a valid page layout. To correct the problem, edit page settings and select a valid page layout."
Then I have tried "download as a copy" and upload the aspx file to another site collection. The same error show up.
May I know is there any easy way to copy this page over 10 site collections? Thank you.
