I recently migrated publishing page library content (pages have webpart zones and content editor webparts) from SP2010 to SPOnline wiki page library using Sharegate.
After migration I am able to view pages and content on wiki page library but when I go to specific wiki page and go to edit mode nothing is visible. I also checked "Wiki Content" column and it's empty for any of the migrated pages. If I create a page on wiki library, content is in "Wiki Content" column.
Here is my question: Where is the content of those migrated pages? Is it in content database and if I'm able to access it programmatically as I have to work further on that data?
