Re: [Urgent] - CDH upgrade v5.4.5 to v5.8 - Cluster to different Cluster upgrade

There are no issues moving within the same major versions.

In Hbase the challenge is only if we move from Hbase 1.x to 2.x. There we
have to take care of MOB, coprocessors, Prefix etc.

Anyway, moving/copying data across clusters does not cause issues. We only
need to worry about in-place upgrades.

When you say distcp, for Hbase do snapshot export.
