> In my testing I have seen a need for performing upgrade testing from 
> local/internal non-public "versions" of Derby.
> That is, having local/internal changes to some older branch and allowing 
> upgrade testing from this (not yet public) version.
> One solution is to locally modify the 'VERSIONS' table of the upgradetests 
> '_Suite', but this means modifying the source for each such case.
> A more flexible solution is to override the default versions (given in 
> 'VERSIONS') by using a property giving a file which lists the versions to 
> test upgrade from. The location to local version jars can currently be given 
> by the 'derbyTesting.oldReleasePath' property. The list of versions could be 
> given by a property 'derbyTesting.oldVersionsPath'.
> This will also easily allow us to skip testing upgrade from a specific 
> version. (This can already be done by not having the version jars available.)
> The list of versions given via the property should be used whether versions 
> (jars) are available locally (as given by the 'derbyTesting.oldReleasePath' 
> property or fetched from the Apache Derby svn repository 
> ('http://svn.apache.org/repos/asf/db/derby/jars').
> I have a patch for this which I will submit for review.
