Upgrading opConfig between 2.x or 3.x versions
Upgrading opConfig is a very simple operation, if your starting version is 2.x. If you are migrating from opConfig version 1.x please check out the separate version 1.x upgrade guide page.
The required steps
Download the new opConfig release
become root and unpack the release tarball
run the interactive installer and follow the prompts
visit the opConfig GUI and confirm your EULA acceptance for the new version
All of these steps are documented in the opConfig 3 Installation Guide.
