drag the page ‘Landing’ beside ‘Home’, then drag ‘Home’ into ‘Landing’.
Then you need to adjust a lot of page IDs in typoscript and move template records around.
use the list view and extended clipboard to move a lot of records around:
- in page
HOMEmark all pages except ‘Landing’ and put in in the clipboard. go to ‘Landing’ to move all pages in the clipboard to this page
- exchange all content from pages ‘Landing’ and ‘Home’: mark all content in one page and move it to the end of the other. then mark all old content from that page to move it to the other. exchange the name of these pages.
In this way the page IDs of root page stays as is. also template records stay at their place.
Be aware that your URLs may change except you configure some slugs to be skipped.
