Important: Before You Upgrade to NorthStar 6.1.x
Consider the following important notes before you upgrade to NorthStar 6.1.0 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 such a way 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, you do not need that 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.
