Scroll Versions should provide an ability to move pages from a versioned to other spaces.
As a workaround, publish the pages you want to move to the target unversioned space:
Click Scroll Add-ons > Attributes.
Create an attribute 'ToBeMoved', add any value like '1'.
Create a Variant 'Move'. Define it as pages with the attribute and value as define in the second step. (leave the _unset_ checkbox empty)
Go to the pages you want to move and add the attribute value to all of them.
Publish the variant to the existing space of your need.
Go to 'Reorder pages' and move the page to the correct hierarchy spot.
