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.
