We need to keep a copy of our legacy data for reporting purposes but our previous vendor is requesting we delete all copies of the old DB. Deleting the data makes no sense, it a very real sense that data is ours, but we're not sure of 'normal' legal ownership of the schema. Does anyone have experience of a previous supplier requiring all copies of a database to be deleted? And how did you address it - flat file export? What about column names etc.
I realise you're not lawyers, but in this instance knowledge of what is normal in the real world is a useful bargaining tool.
