Procedure
- Go to the page you want to move.
- Open the page in the "Edit" mode.
- If you see yellow EDIT button under the page title, next to Location, click on it. If you see a yellow DONE button, skip this step.
- If you are moving a page to a different space, select the space from the Space drop down menu.
- Fill in the Parent Page or use the Choose page tool (
) to select the appropriate parent page. - If moving a page with children to a different space, you can specify if you want to move the children as well. Within the same space children are always moved with the parent page.
