Switching to Minimal Template

Summary:

Splash page disappears upon changing to Minimal from Modern Template

Content (required):

Our client has an external career site with a Splash page and a Custom Page in Modern Template. As per Oracle's advice for us to move on to Minimal template by 23B we are testing the same and followed the below steps

Duplicate existing careersite --> Themes --> Change the Modern template to Minimal --> Goto Pages tab and see that the 'Splash' page has disappeared . Is this supposed to be so ? Shouldn't it retain the Splash page ? Are we to create the Splash page from scratch ? Please advice
