IRIS RDA upgrade overview

This chapter describes how to upgrade from IRIS/RDA 10.0.0 to later releases.

The upgrade is handled by the DNF package manager installed by the IRIS 10.0.0 installation script. In the upgrade process, the DNF replaces existing RPMs with new RPMs.

The upgrade process includes the following steps:

  1. Back up your configuration files. See Preparing for the upgrade.
  2. Get the latest software release ISO image and Release Notes at https://ftp.sigmet.com/files/releases/. See Getting upgrade software.
  3. Run the install script. DNF identifies new versions of RPMs included in the installation image, and automatically triggers the upgrade process to higher versions. See Running the installation script.
  4. Run the Setup utility. See Running Setup after upgrade.
