Page Redirection

Hello,

I am trying to simulate a migration scenario in SharePoint Online and am running into a limitation I cannot resolve.

For demo/testing purposes, I have two SharePoint Online sites (e.g. Old and New). I would like to redirect a small number of individual pages from the old site to corresponding pages in the new site, while the rest of the old site remains unchanged.

Example:

Redirect

https://ps3c.sharepoint.com/sites/Old/SitePages/Test.aspx

to

https://ps3c.sharepoint.com/sites/New/SitePages/Test.aspx

The page is a modern SharePoint page, and the URL itself is fixed for the purpose of the demo (i.e. users or tools open the page directly on *.sharepoint.com).

All documentation I could find only describes redirecting entire SharePoint sites, not individual modern pages. Client-side approaches (JavaScript, HTML meta refresh, etc.) also appear to be blocked in modern SharePoint.

Is there any supported or recommended way in SharePoint Online to implement page-level redirects for modern pages, or is this currently not supported by design?

Kind regards
