Downgrading to a Previous Release

Package Downgrade

The existing NuoDB package must be fully uninstalled and the downgraded package reinstalled.

The rpm --oldpackage command cannot be used.

Database Downgrade

It is possible to downgrade the database between NuoDB maintenance and patch releases. For example, from NuoDB 4.0.7-1 to NuoDB 4.0.5-4.

It is also possible to downgrade between NuoDB major and minor releases if the upgrade database command has not yet been run. See Upgrading the Database Protocol.

Reinstalling an older release where downgrade is not supported requires stopping the database, loading a backup copy of the archive from before the upgrade, and restarting.
