Downgrade 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 Upgrade 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. |
