Hi Xiaoxiang, CubeMigrationCLI.java can migrate a cube from a Kylin environment to another, for example, promote a well tested cube from the testing env to production env. Note that the different Kylin environments should share the same Hadoop cluster, including HDFS, HBase and HIVE.
Per the document, cannot migrate across cluster? We are finding a solution to do this and QA & PROD are in different cluster. Can you help give more advice?

See that cannot use CLI to migrate data from QA environment to PROD if they are in different cluster, what's the limitation when migrate across clusters and then how can do the migration? 2. We have tried with metastore.sh backup and then restore in another cluster, Will this be a solution for migration? And any impact if using this solution?
