Thanks, Deepa. Given the importance of this feature on Derby's dependability and ease of use, A Wiki page on this would be wonderful, if anyone is so inspired.

Is there a document for developers somewhere that explains the kinds of

(although I'm pretty darn sure i18n changes in the client don't impact
upgrade :) ).


I don't think there is a document which summarizes the kinds of
changes that may impact upgrade. I think this article helps:
http://db.apache.org/derby/papers/versionupgrade.html. Other than
that, the various discussions are spread out in the mails.

For adding tests, please look at the case* methods in
org.apache.derbyTesting.functionTests.tests.upgradeTests.UpgradeTester.
I'll try to add information about the test to a Wiki page.

Thanks,
Deepa
