It was a quite different situation when they moved the Chaos servers from NA to Europe. In that case they either had to move the physical servers across the Atlantic, or (more likely) copy all the data over a cross-atlanic link. Either of those take time.
For the upcoming data center split all servers will remain in the same room they are in. Only things that will need to change is how cables are connected between switches and routers, and some configuration settings. If it has all been properly prepared it shouldn't take more than a few hours to set things up.
I think it will be longer than a day especially given the wording.
