only latest data preserved

Well, I've got the Wiki working again. But there is a major restriction for historical data--it can not be accessed.

The problem is that only current meta data is used. Data stored in properties that do not exist can not be accessed. And only "latest" data got converted.

Definately puts a crimp in things.

The lesson here is that to preserve historical data, you need to convert the .dmp file, rather than operating on just the current state of the database.
