But really, OMG, finally. I tried the process and it worked. Goodbye, legacy account I've been dragging along with me for the last decade!
Edit: "Make sure both accounts are set to the same country and region for purchases." Arghh!
This is a setting nowadays, meaning that you can now change that for any account now. I have done that a few times already.
Owned purchases may have some sort of import fee to account for lost tax revenue to make sure not purchased in country with lower tax then transferred which may be very complex to calculate.
Media/music especially is often edited/licensed for a specific country and only offered in a specific language per country. I’d prefer if Apple owned up to being a premier media outlet by providing every cut, sub and dub offered in every country for a single purchase in any country, but I am sure it saves Apple a few pennies on network transport and translator fees to restrict the options. If they could get a music contract allowing for original songs any director used originally that would be cake. Just imagine learning a languages by watching the original cut of your favorite movies in other languages. If Eddy Cue wanted to leave a memorable legacy it would be remove as many region restrictions as possible creating a class of global citizens.
