Upgrades in AWS Elemental Delta

This section describes how to upgrade the software version of an existing Delta installation.

Important

To avoid service interruptions, perform upgrades during a maintenance window! All traffic to and from an AWS Elemental Delta node stops while the node is being upgraded.

When you're upgrading AWS Elemental Delta nodes, the basic command remains the same, regardless of how many nodes you have. The command you use is this:

[elemental@hostname ~]$ sudo sh ./elemental_production_delta_<version>.run –-skip-all

where version is the software version that you're upgrading to, such as 2.3.0.123456.

If you have a cluster of nodes, though, they must be upgraded in a specific order, and extra steps might be needed. For this reason, this section includes separate topics for the different kinds of clusters.
