Experimenting with Launchers. How to migrate desktops?

[Tsukiyomi]

So the move over to ICS has led to me trying out different launchers, although I'm not too unhappy with the ICS (i.e. 'Launcher') one that I'm using in place of TW. I've now just installed Apex and it seems pretty good but one thing is going to make me give up the whole process and that's the tedious process of having to recreate all of my Screens.

I tried Desktop Migrate and that did sod all. It asks me what I want to copy then, as if by magic, does nothing at all. So are there any other options for copying Apps, Widgets, Folders and layout from one Launcher to another?
