Upgrading from Release 22.6 or earlier

Upgrade process

An upgrade from Release 22.6 or earlier involves moving from RHEL 7 to RHEL 8, so is essentially a platform migration that involves the following high-level steps.

1. Upgrade the NSP software in place on the existing RHEL 7 auxiliary database stations.

2. Restore the auxiliary database on the new or recommissioned RHEL8 stations.

Note: CPU frequency scaling must be set to “performance” in the BIOS of each auxiliary database station, or the auxiliary database upgrade fails. See the RHEL power management documentation for information about enabling the “performance” CPU frequency scaling governor on a station.

Setting CPU frequency scaling to “performance” effectively disables the function, so may result in greater energy consumption by a station.

Note: Enabling TLS on an auxiliary database is not supported during an upgrade.
