Upgrades in AWS Elemental Statmux
This section describes how to upgrade to AWS Elemental Statmux version 2.20.x.
Upgrade rules
The following rules apply when you're upgrading AWS Elemental Statmux software.
Your system must be in a working state prior to the upgrade. If it's in a degraded state (such as not accepting MPTSs or not responding through the web interface), the upgrade fails.
You can upgrade to a version that's a maximum of two major versions above your current version, such as from 2.17.x to 2.20.x. The number of patches between the two versions is irrelevant. To upgrade over a bigger span, you must perform several upgrades, such as from 2.15.2 to 2.17.4, then to 2.20.0.
Important
Plan to upgrade during a maintenance window. All activity on the nodes stops during upgrade.
