@MojangSupport Hi. I'm having an infuriating time trying to migrate my old Minecraft account to Mojang. I made my account during an era where an email wasn't required. Nonetheless, I can't migrate my account without detailing the nonexistent email associated with the account.
Please send us an email at https://help.minecraft.net/hc/en-us/requests/new … and we will assist. Remember to attach your Transaction ID. ^SP
