You have to keep in mind that you'd have to build out actual fulfillment capabilities on a brand new platform (so you need training of a ton of staff on a new system, as well as a bunch of new equipment to print orders from the "temporary" systems in the warehouses/stores hopefully without removing the original systems they're trying to restore), plus who knows what the database backups looked like. Plus inventory is going to be all screwy with sales happening to some degree in stores (what POS is that using? Is it decrementing inventory we can use?) I'd sure not bet my reputation on having a shoppable site up in less than several weeks without knowing if I have at minimum, reasonably accurate catalog and inventory data.
