I was under the impression you were interested in modifying all
versions of instances even old ones. Even those can be found during a pack
operation at least the pack operation in dbmStorage does find them. If 
only the 'current' versions are to be modified then things get a lot
easier (a python script will do I suppose), unless someone is continously
updating the relevant instanceas you've mentioned.
