Upgrade Path from HDP 2.1 to HDP 2.3.2

[#1]

Hi,

What is the best upgrade path from HDP 2.1 to HDP 2.3.2 ?

[#2]

That is a supported upgrade so I believe the direct upgrade from 2.1 to 2.3.2 would be the optimal path

@awatson@hortonworks.com - Did you take a look at the upgrade guide for 2.1 to 2.3? http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.3.2/bk_upgrading_hdp_manually/content/ch_upgrade...

We already had some clusters going from HDP 2.1 directly to HDP 2.3.2 and apparently only minor issues along the way, nothing serious though.

Ambari 2.1.3 will support Express Upgrade from HDP 2.1 -> 2.3 directly. That feature is similar to Rolling Upgrade, except that the cluster takes downtime. ETA is December.
