4.2 Prerequisites and Considerations for Upgrading NICI

Before upgrading NICI, review the following considerations:

  • Reinstalling NICI does not destroy existing keys.

  • Installing NICI 3.0 or later does not require rebooting the server in most instances. However, if the NICI module (DLL or .so) is in use and cannot be overwritten by the installation program, a reboot might be necessary. Before installing NICI, all applications using NICI should be shut down to help avoid reboots.

  • Installing a newer version of NICI over an existing NICI installation upgrades NICI. Always upgrade NICI using the NICI installation program (MSI or RPM). Do not copy NICI modules manually. Manual copying will result in a chaotic system, and will often cause irreparable damage to the system and/or other products such as PKI, SecretStore/Single Sign-On, NMAS, directory services, etc.
