How to “modernize” classic SharePoint pages on-premises?

Question

We need to "modernize" SharePoint pages after migrating from SharePoint 2013 to SharePoint 2019. Which options do we have?

There is lots of documentation around modernization and respective tooling here in the Microsoft docs but this seems to apply only to SharePoint Online. Which is a pity.

Which options do we have on-premises?

Answer 1

The only current method to modernize is to recreate the pages.
