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
