Hi, I need to migrate one jackrabbit repository.
My old repository.xml is: repository_old.xml
My new repository.xml is: repository_new.xml

For migration I download jackrabbit standalone server and execute:

java -jar jackrabbit-standalone-1.6.0.jar --backup -r C:\data\jackrabbit\data -c C:\data\jackrabbit\repository_old.xml -R C:\data\jackrabbit\data-backup\ -C C:\data\jackrabbit\repository_new.xml

When I execute command after some time I see exception:

Exception in thread "main" javax.jcr.RepositoryException: Failed to copy content: Unable to copy org.apache.jackrabbit.core.state.NodeState@1ca1588: failed to write node state: a7e21876-13cb-465c-8489-f402e53e9193: Unable to copy org.apache.jackrabbit.core.state.NodeState@1ca1588: failed to write node state: a7e21876-13cb-465c-8489-f4

Do you have an idea what the problem is and how I could migrate repository? My new repository is configured to work in cluster.
Thanks
