Based on the post by Blizzard the length has to do with how they are working with the databases. They are doing this in a way never done before.

Data in World of Warcraft lives in three databases, the Persistent database (your characters, guilds, items etc), the Account database (account level things like achievements) and finally the Regional database (handles region wide things like Token, character numbers on the Realm List). On Tuesday, we will be copying all your Account and Regional data to the new environments database, that’s what will be taking up the majority of the downtime. As for your Persistent data, that’s where we’re bending some long establish rules for how we do World of Warcraft infrastructure.

These “new” realms on this new environment will be using their old Persistent data, on their old database that is also still busy serving Classic Era. This is new, we’ve not done anything like this before, when the database engineers pitched this plan the initial reaction was, "wait that really works? but testing has proven that yep, it really does! For any database minded folks out there, we’re talking two different versions of World of Warcraft reading and writing to the same database when normally each environment would have its own database.
