Since Feb 1, 2015 Apple forces iOS developers to supply a 64-bit binary when submitting new apps to the App Store.

For app updates this got relevant on June 1, 2015.

So, you're right, you'll need a 64-bit binary to submit an update of your app.
iOS 64-bit support was added in version 4.6.2

Unity coded a new compiler IL2CPP
that is capable of 64-bit, and that's the only way to create 64-bit builds with Unity.
As this new compiler is quite new (and still has a lot of bugs), I'd recommend to stick to the latest version of Unity 4.6.x (or 5.x, if you want to). The newer version include a lot of bug fixes, especially for IL2CPP
.
We're using Vuforia SDK 4.0 together with Unity 4.6.6 (I'm sure it also worked with 4.6.5) and Xcode 6.3.1.

Note: The IL2CPP compiler doesn't really deliver feedback on its progress, so the build may freeze Unity for a couple of minutes (depending on the projects size). Just wait until its finished.
As Xcode stripped to much code by default, we needed to reduce the optimization level in the Xcode project.

If you got this far, it should be working now ;-)
