Upgrade SolarWinds UDT 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.
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:
|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.
