I think they can get basic functionality and flow up by the end of the week with enough staff and resources thrown at it. Full functionality and maximum flow... well, we’ll see.

Depending on how much they need to flash to the PLC’s and SCADAs.
If they have the backups. If they don’t, then there is a LOT of tuning and integration before they can turn on flow.
Having been in an event where a lot of drives needed reflashed.. Well I developed a taste for bad Scotch.
