Soon the Mojang accounts will be replaced by Microsoft accounts. So what happens to the 2nd accounts because I don't have a 2nd Microsoft account
Just create a second Microsoft account?
I'm not in the mood for that
Then you have to create a second Microsoft account. It's easy to do here:
I would then have to create a new email address etc.
This will take no more than 5 minutes
According to an unofficial source, the non-migrated accounts will be deactivated after the account migration phase ends. But I would wait until then, because more information will be announced then.
Is so
Does deactivated mean deleted or just like that I can no longer launch minecraft until I do the migration?
What should happen with it? You already have 2 email addresses if you have 2 accounts.
Yes and no the second email is icloud
Yes, that's also an email address. In the future you will just need a second Microsoft Mail. Otherwise nothing changes.
I think it was meant that the account is deactivated and you can't migrate it. However, nobody but Mojang knows how it will all work out.
