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
