Important: Before You Upgrade to NorthStar 6.2.2
Consider the following important notes before you upgrade to NorthStar 6.2.2 from a release earlier than 6.0.0:
As of NorthStar 6.0.0, we no longer support CentOS or Red Hat Enterprise Linux (RHEL) 6.x. To help with your operating system migration, we are providing a procedure for upgrading your operating system in so that your clusters and data remain intact. See Guidance for Migrating to CentOS 7 for NorthStar 6.0.0 and Later in this Release Notes document.
If you are already using CentOS or RHEL 7.x, please disregard this section.
As of NorthStar 6.0.0, due to a change in the way the netflowd parameters are stored in NorthStar, you must copy all netflowd-related configuration in the northstar.cfg file to the northstar.cfg file on all your application servers. There are two exceptions: “netflow_collector_address” and “netflow_port” should remain on the analytics servers.
