Unlink two spaces
When you unlink a draft source space and its published target space, the content remains the same in each space - no content is deleted or changed when you unlink the spaces.
Unlink draft and published spaces
To unlink two synchronized spaces
Choose Space Publishing in space tools
Choose Configure
Select Unlink from ... in the Target Space dropdown menu
Save
The two spaces are now unlinked.
The space tools will display a message confirming that the current space has not been configured for publishing.
