Upgrade SolarWinds NTA with HA

To upgrade a server pair in a SolarWinds High Availability (HA) pool, follow the instructions for upgrading your product with the following differences.

If you enabled SolarWinds High Availability, you must disable HA before you can upgrade. All SolarWinds product versions must match on the primary and secondary servers before you can re-enable your HA pools.

These instructions assume you have an HA pool already created and enabled.

1. Disable the HA pool

The HA pool must be disabled to begin upgrading. If you upgrade prior to disabling, the pool is automatically disabled.

  1. In the Orion Web Console, click Settings > All Settings > High Availability Deployment Summary.
  2. Select the pool you want to disable.

  3. Toggle High Availability to Off.

Do not modify the VIP or IP settings for the servers.

2. Upgrade the primary server Follow the upgrade instructions in the next section for the primary server. If you need to upgrade multiple products in the upgrade path, complete those upgrades fully.
3. Upgrade the secondary server using Orion Scalability Engine Installer

Download the Orion Scalability Engine Installer on the primary server and run it on the secondary server to upgrade:

  1. In the Orion Web Console, click Settings > All Settings > Polling Engines and click Download Installer Now.
  2. Move the downloaded installer to your secondary server and run it.
  3. Complete the installation process. You may be prompted to enter your SQL credentials for your Orion SQL database.
4. Enable the HA pool

When the installer completes, enable the HA pool using the following instructions. You may need to recreate the HA pool. For details, see this article.

  1. In the Orion Web Console, click Settings > All Settings > High Availability Deployment Summary.
  2. Select the pool you want to enable.

  3. Toggle High Availability to On.
    The Orion Web Console verifies all SolarWinds product versions match across the HA pair before enabling. If you receive errors, check your product versions.
