site folder transfert

Hi again! 🙂

I’m trying to move WP from a mydomain1.com/folderA/ to mydomain2.com/

Installer.php has been upload to mydomain2.com/folderB/
Step 1 Deploy is ok.
Step 2 Update : I give those information:

New Settings
URL : mydomain2.com/folderB/
Path : “the root html directory”/folderB/
Title : unchanged

Advanced Options…
Site URL : mydomain2.com/

Then install is complete.
But when I try to reach mydomain2.com/folderB/wp-admin/options-permalink.php

it give me a 404 (adress point to http://www.mydomain2.com.com/wp-login.php?redirect_to=http%3A%2F%2Fwww.mydomain2.com%2FfolderB%2Fwp-admin%2Foptions-permalink.php&reauth=1 )

Any idea?
Also, is there a way to move the entire install to the root folder?

Thanks for your help!
