Issue with content migration to Sharepoint 2019 On-Prem

MichelleARC 0 Reputation points

We are updating our Sharepoint site from 2010 to 2019 on-prem. We migrated the content to 2019 and the navigation migrated as well. However, when I access a page from the navigation, while in Modern view, it takes me to a page in the Classic view, with a page not found error. How can we keep the full site in Modern view, without the navigation taking me to a page in Classic? Is there a setting in the farm that needs to be adjusted?

    Hi @MichelleARC ,

    There is no way to realize upgrad or convert the old Classic Pages to Modern Pages. You may need to manually create new Modern Pages.

    "Page not found error", please check if the page is deleted and exists in the recycle bin.
