Problem with home

Hello,
I would like to give the example of my problem and hope you can help me.
I have a website: https://www.nome.com and had problem with the template configuration and ended up doing another home with the name: https://www.nome.com/destaque.
Now I need replace the first or the second is to make the https://www.nome.com/destaque would become https://www.nome.com but do not know how to change the permanent link for replacement.

Thank
