Copy Marklogic Data between Marklogic Servers - mlcp

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.

Install mlcp

Use mlcp only if you have Marklogic 6.0 or above. If not, use XQsync instead.

1. Download mlcp binary zip package.
   
2. expand downloaded marklogic-contentpump-1.0.3.zip
3. cd to <installation-dir>/marklogic-contentpump-1.0.3/bin/

Copy Marklogic Data

To copy from one Marklogic server directly to another, e.g.,

./mlcp.sh copy -help
./mlcp.sh copy -mode local \ 
 -input_host host1 -input_port 8020 -input_username admin -input_password admin \ 
 -output_host host2 -output_port 8006 -output_username admin -output_password admin \ 
 -thread_count 8

Export Marklogic Data

To export Marklogic Archive from one server,

./mlcp.sh export -help
./mlcp.sh export -host <server> -port <port> \  // 1
    -username admin -password admin \
    -mode local \                                                // 2
    -directory_filter /content/cq/ \                       // 3
    -output_file_path /tmp/testcollection -output_type archive

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

Import Marklogic Data

To import a Marklogic Archive into another Marklogic server, e.g.,

./mlcp.sh import -help
./mlcp.sh import -host localhost -port 8006 -username user -password passwd \
-input_file_path /space/bill/data \
-mode local
