App store listing name availability after name change

We have an existing app called "abc". We want to rename it to "def". We have another new app called "ghi" and we want to name it "abc".

We know it's possible to name "abc" to "def" with an app update on the existing app.

  1. The question is, after how long will the name "abc" become available to use, so we can name our new app "abc"?

  2. Will simply putting the name "abc" for new app on AppStore under "General -> App Information -> Name" suffice?

Thanks in advance!
