Do we agree in the target db schema? That's the important point.
We haven't thought about it in detail. But it would be a fairly large change and require changes throughout the software, as well as possibly elsewhere in the schema.
Migrating a large site like commons is 'just' an operations issue. Making it readonly a bit wouldn't be a big issue, but could also for instance move to an intermediate point, where uploads are stored in both formats, while read only in the old one, while a script is moving records. Finally, flip the switch and drop the old tables.
Sure, it can be dealt with. It's just that it'd be an epic upgrade :)
