Hi,
In Kentico 9 you have the new CI feature which also includes pages, but I assume you're not using Kentico 9 yet :).
The export module has the option to export documents... but it's either all or only changes since date x. But the GUI doesn't show you which pages it includes. Only after starting the import you see the pages passing by.
Their is another option I used a few times when I imported and altered over 500 pages on development and they didn't exist on production yet. This however is only useful if it's over 100 pages. Otherwise I'd say get some people together and create them by hand. You'd be surprised how fast this go's :).
- create and restore a complete copy of your dev database locally
- in that installation you remove all other pages you don't need
- create a new site export and only select the documents
- import these in your target server
In my case it was however a folder directly under the root, so no other content was overwritten.
note: remember media library images aren't included. What ever you do make sure to create a backup first.
Hope this helps!
Greets,
David
