After migrating from a classic site to a modern site, you can use a solution provided by Microsoft and PnP Community to convert classic pages within the migrated site to modern pages via the Content Matrix Console.  

IMPORTANT: The assemblies required to run this action are not shipped with Content Matrix and must be obtained from the PnP Community.  If you initiate a Convert Classic Pages to Modern Pages action and the assemblies are missing, a pop-up message will display which includes a link to a Knowledge Base article with step-by-step instructions.  Quest does not provide support for this solution, as Content Matrix only provides users with the capability to run it.  

Supported Objects

The Convert Classic Pages to Modern Pages action converts all applicable classic pages and their web parts to modern pages.  It is available for the following objects:

Site Level:

· Team Site with no Office 365 group (STS#3)

· Team Site with Office 365 group (GROUP#0)

NOTE:  Currently, Content Matrix does not support migrations to this site type.

·Communication Site (SITEPAGEPUBLISHING#0)[

Note that site root pages will also be converted

List level:

Document libraries within a supported site type.

Item level:

Classic pages in a document library within a supported site type.

Converted Page Naming Conventions

Converted modern pages are saved in Site Pages library, along with the original classic pages. By default, the converted page uses the same name as the classic page and the classic page is renamed “Previous_<original_page_name>.aspx.”  If you want classic pages to retain the original name (and continue to display using the existing url), you must change the value of the configuration variable TargetModernPageTakesSourcePageName in the Application Settings.xml file to False.  The modern page will then be named "Migrated_<original_page_name>.aspx; however, the content approval status of the classic page will be changed from Draft to Pending, and a new version of that page will be created.

To convert classic pages to modern pages:

1.Select the object whose pages you want to convert.

2.Right-click and choose Convert Classic Pages to Modern Pages.

NOTE:  This menu option is available only for supported objects.

You can monitor the progress of the action in the Job List.
