Hi All, I need to migrate existing MySql DBs used for metastore, cmserver, amon, rman, oozie, hue and sentry to another MySql DB instance (MySql version 5.5). We are using CDH 5.16 and it contains 300TB data. Migration need to be done smoothly with less interruption to production workload. Appreciate if you can share the instructions/ related documents to do this.  Thank you ... View more
