Generally I'd only have at most 2 formats at once while you converted the older records to the new format. You're right that there's no sense in keeping around a dozen versions but there are a lot of business cases for having two versions of a schema active at once. For example, if you can't bring down your application to convert everything mid-day and instead want to do an incremental conversion. |
