Return to top

For information about installing NetFlow Traffic Analyzer, see the NTA Installation Guide.

Starting with NTA 4.2, the NTA Flow Storage Database is no longer supported on additional pollers and additional websites, and needs to be installed on a dedicated server. This includes NTA versions 4.2.1 through 4.2.2.

Before you upgrade

If you are upgrading from a previous version, be aware of the following considerations:

  • When upgrading to NTA 4.2.2, if you added a site binding to a host name before you upgrade, you must bind the Orion Web Console to a fully qualified domain name (FQDN). See this article.
  • When upgrading to NTA 4.2.2 with custom menus, you can not see the Performance Dashboard link in the menu. For details, see this article.
  • After NTA 4.2.2, future releases will no longer support Windows OS 2008 and 2008 R2 and Microsoft SQL Server 2008 R2. NTA 4.2.2 currently supports these versions. SolarWinds recommends that you upgrade to Windows Server 2012, 2012 R2, or 2016 at your earliest convenience. For more information, see Deprecation notices notices.
  • Always use the Product Upgrade Advisor to build your upgrade path.
  • Always upgrade NPM first. NPM includes platform features to support all Orion products. See the NPM Upgrade Guide for more detail.
  • See the NTA Upgrade Guide for more detail.

How to upgrade

If you are upgrading from a previous version, use the following resources to plan and implement your upgrade:

  • Use the Product Upgrade Advisor to determine your upgrade path. Based on your current environment and versions, the Product Upgrade Advisor provides an ordered list of how to proceed with the upgrade.
  • Use the multiple products upgrade guide for upgrading NTA and other modules (NPM, SAM, NCM, etc.). Each guide includes checklists and instructions to help you plan and execute your upgrade.
