Druid upgrade from 0.13.0 to 0.14.2


I have a Druid 0.13.0 cluster running. Have a plan to upgrade the version of Druid 0.14.2. In my case, need to recreate the a new Druid cluster with 0.14.2 version pointing to the same MySQL metastore and S3 deep storage. What are the steps involved? Do I need to take care of anything while going for the upgrade to avoid issues like data corruption etc?
