How to Upgrade Security Server to RHEL 8 Using a Configuration Backup?

This document describes the steps required for migrating a stand-alone Security Server from an existing RHEL 7 host to a new RHEL 8 host. The migration is done taking a backup of the Security Server configuration on the RHEL 7 host and restoring the backup on the RHEL 8 host. Please read carefully through the whole document before starting the upgrade process.

This document assumes that you are using two different server hosts concurrently during the upgrade process: 

  • old server, which runs RHEL 7

  • new server, which runs RHEL 8.

Terms old server and new server will be used to refer to these.


  • Connecting a hardware security module (HSM) to a new server may require additional steps that are not covered by these instructions. Check the HSM documentation and verify that it supports RHEL 8.

  • Ensure that both servers run the same X-Road version and PostgreSQL version.

  • On the old server, use the admin UI to take a backup of the Security Server configuration and download it to a safe location.

  • In order to route traffic to the new server after the upgrade is complete, prepare to update your network configuration.

    • After the upgrade, you may need to change the new server's public IP address(es) to match the old public addresses and/or update DNS,  firewall, NAT, or other network configuration so that other Security Servers and your information systems can reach the new server. The exact steps depend on your network setup and are not covered in this guide. Note that if the publicly visible IP address of the upgraded Security Server changes, you may need to contact your X-Road Instance operator and/or other members for firewall rule changes.

Upgrade process

Reducing the size of the message log database dump: By default the message log database keeps 30 days of message records but one can (temporarily) change the retention time in order to reduce the number of records in the database, thus reducing the size of the database dump. Changing the setting has no immediate effect since by default the message log cleanup is run twice a day (noon and midnight). See Security Server User Guide: 11.1 Changing the Configuration of the Message Log for more information.

  • Optionally, copy the operational monitoring database from the old server (if xroad-opmonitoring is installed).

    • On the old server, stop the xroad-opmonitor process and dump the database:

    • Copy the dump to the new server and restore the database on the new server:

  • Switch over to the new server (stop the old server and update your network configuration accordingly).

    • For example, change the new server's IP address(es) to match the old addresses and/or update DNS, firewall, NAT, or other network configuration.
