It's actually pretty easy. All you have to do is to go into your account and under the payment information tab, change your country, then hit save at the bottom of the page. You don't have to change the rest of your address at all. Sometimes the postal/zip code is incompatible with the new country's format and if you enter the suggested number it will be accepted.

The book appears in your account just like any other book bought from your country's specific Kobo store.

I haven't done it a lot so others with more experience will probably have better advice.

Edit: Also, you have to have the payment information cleared before you can change locations.
