How do I get a list of pages/folders created/modified by a user?

Hi,

You can use query builder to fetch the pages which are created by a specific user and write a service to create content package which can be used to install in other instances.

path=/content/we-retail/language-masters/en

1_property=@jcr:content/jcr:createdBy

1_property.operation=equal

1_property.value=rpampana

p.limit=-1

Creating content package:

Adobe Experience Manager Help | Creating Adobe Experience Manager Packages using the JcrPackageManager.API

Similarly we can write query for modified data
