I imported Startup Business Demo but there are certain pages I would like from Default Demo and Minimal Portfolio Demo.
The thing is im afraid it could overwrite the pages I already have.
What will happen when I import Default Demo and Minimal Portfolio Demo ? Will that overwrite my existing pages ? ( I want to add those pages, not to replace them)
The pages will stay the same but your settings will be overwritten. What you can do is export your settings in Dashboard > Enfold > Import/Export and then import them again after doing the demo import.
A lot of posts, images, pages, and other content will be imported as well so it might be a chore deleting everything you do not need so please keep that in mind.
