This part is at the bottom:

You do have a Rovio Account and have already synced:
To Backup To transfer and/or restore your progress:
 * 1) Open up DiskAid as your normally would
 * 2) Backup the four files: highscores.lua, settings.lua, highscores_ .lua, and settings_ .lua.
 * 1) Logout of your Rovio Account and completely close the game
 * 2) Open up DiskAid (if not already)
 * 3) Copy all four files: highscores.lua, settings.lua, highscores_ .lua, and settings_ .lua to your new device
 * 4) Launch the game and log back in
 * 5) Your new progress should be there and pushed up the cloud.

Questions
I imagine there will be more, but wanted to get some thoughts down nonetheless. We weren’t the first time we tried, but that might be a nice “just-in-case” feature to add. I’m not even sure if this is possible, but this is yet another reason to manually backup. As far as I can tell, so long as you provide different email addresses this shouldn’t be an issue. We don’t know just yet, but would assume that is the ultimate goal. We touched on this above. At this time it doesn’t look like it. I personally don’t think this will ever be supported, but who knows.
 * 1) Will it prompt you to overwrite your progress?
 * 1) What happens if old progress gets loaded onto your device?
 * 1) Can I create multiple profiles for different progress?
 * 1) Will it work across platforms?
 * 1) Will it merge my progress (i.e. just take my highest scores)?
