Downgrading to a Previous Release

NuoDB supports downgrades between patch releases of the same maintenance build. For example, downgrading from version 2.6.1-8 to version 2.6.1-5 is supported.

NuoDB does not support downgrades between and within major, minor, or maintenance releases. For example, downgrading from version 2.6 to version 2.5 is not supported, and likewise, downgrading from version 2.6.1 to 2.6 is also not supported.

Note: 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.
