Dear Érico,
addressing the migration problem via forum has a better multiplicator than individual mails, and more eyes can spot different problems. Normally, there is no need to send/show the full error.log since later errors are typically consequences of earlier errors. Find in your error.log the place where the server starts and search for the first "Error:". Post this with a context of about 20 lines here....
all the best
