Introduction

This document outlines the procedures for upgrading Jetstream DR AVS.
The upgrade process involves updating MSA, Plugin, DRVA/RocVA/Cluster, and performing clean-up afterwards.
It's essential to understand that not all JetStream versions require upgrades for all components.
To ensure a smooth upgrade experience, it's advisable to adhere to the prerequisites

Note: Roll-back options are not supported.
Since the JetStream DR has multiple components (MSA, DRVA, IO Filter, Plugin etc..) the Rollback/revert to an older version from a new version is complex and not recommended. VMware does not support rolling back the IO filter and plugin.

The time taken for the overall upgrade process depends on various external factors (like enter/exit ESX host maintenance mode) that JetStream cannot influence. So, the total time taken varies.

Prerequisites

The following prerequisite conditions must be met before attempting to upgrade JetStream DR for AVS:

  • Select a window of time to perform the upgrade process when relatively low IOPS will be used by the system.

  • Verify and confirm the integrity of all JetStream components, ensuring they are error-free.

  • Before proceeding, check and resolve any previously unsuccessful update tasks.

  • Execute a clean-up operation using the command "js_upgrade.py clean -v" before initiating the new upgrade.

  • Validate and ensure all the ESXi host IOF Storage/VASA providers are online: vCenter -> Configure -> Storage Providers

  • Ensure there are no active Affinity rules [ ESXi ] that might affect the host's ability to enter maintenance mode.

  • Verify the health of all vSAN objects. Navigate to: vSAN Cluster > Monitor > vSAN Skyline Health - Data - vSAN Object Health

  • Confirm that no resync operations are currently running in the vSAN cluster. Resyncing can affect the maintenance mode process. Monitor the ongoing resync activities at: vSAN Cluster > Monitor > Resyncing Objects.

  • It is advisable to temporarily suspend any scheduled backups (snapshot-dependent ones) during the DRVA upgrade activity to prevent backup failures (any snapshots taken during this time will fail).

Upgrade Steps

The AVS command “Update-JetDR” is employed to perform the JetDR version upgrade.
This single command efficiently manages the upgrade of all JetDR components to the latest version. Additionally, it includes a resume feature, allowing the continuation of upgrades from any previously failed upgrade task.
