We have a old CDH3 based cluster and we have data stored in HBase on this cluster. We also have brand new cluster in which CDH5.2 is installed.

We want to move HBase data from CDH3 cluster to CDH5 cluster.

I would like to know if it is possible to migrate data across different versions?

Is it straight forward like using distcp command?

What precautions I need to take before migrating data and during migration?
