I attempted to migrate my account multiple times without any success. Mojang support never responded. I searched in unofficial channels and was told the typical response time is multiple months. It was at that point I realized the 10 bucks I paid however many years ago probably isn't worth this amount of effort.
I'm baffled by how good minetest is now. Don't get me wrong they don't have feature parity with minecraft and likely never will. But the fact that they built the game as a voxel engine where people can add mods on top of it to make a full game is such a good idea! (eg. the default "minetest game" is a mod on top of the default engine, you can play other games)
Big plus for me: mod installation is seamless and when you want to join a server with other mods you don't have to install them locally.
Of course it still needs a lot of polish but it is really fun to play.
