As part of Marklogic 6.0 release, a new Marklogic Supported tool named Marklogic Content Pump (mlcp) let you copy/move/migrate/shift data from one Marklogic server to another. If you're using Marklogic below version 6.0, the way to do this is to use XQsync to import/export Marklogic documents and metadata.
To copy date between servers, you can use the mlcp copy command. Alternatively, you can use mlcp export command with an output type of archive (that includes content and metadata) to create a database archive. Then use the mlcp import command to copy/import the archive to another database to complete migrating the database contents.
Use mlcp only if you have Marklogic 6.0 or above. If not, use XQsync instead.

Export Marklogic Data

 XDBC server and port on which XDBC server is running to export data from.
 mlcp transparently splits work among multiple threads on a local/single machine.
 Limit the dump to /content/cq/ directory
