Often, one would want to ensure that the new version is fully
compatible with the application's use of Derby. While Derby is mostly
upwards compatible, occasionally changes introduce minor
incompatibilities even between minor versions, although we do try to
avoid that. Any such items are clearly marked in the relase notes of
that release.

So, depending on your use of Derby, doing an "automatic" upgrade can
be risky or not. If in doubt, consult the release notes of the version
you are upgrading to (and any intervening release notes if you have
skipped some releases before upgrading).

Finally, it is always prudent to take a full backup before you attempt
a hard upgrade.

Hope this helps,

Dag
