Hi, I am upgrading from 1.3.8a to 1.3.9h

I follow the steps on the upgrading guide. Now I come to the export and import database step. I followed the guide here:
https://www.zen-cart.com/tutorials/i...hp?article=103

I have successfully export the backup file. However, when I create a new database and try to import the backup, error occurred:

Error
SQL query:
--
-- Database: `MY_DATABASE`
--
CREATE DATABASE `MY_DATABASE` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;


MySQL said: Documentation
#1044 - Access denied for user 'MY_USERNAME'@'%' to database 'MY_DATABASE'



The original Database is using mysql version 4.1. I tried to create new database with both 4.1 and 5.0, but both failed importing.

Then I tried not to export and import from the phpmyadmin. Instead, I chose 'backup' from the hosting control centre. A database backup is created in my FTP dirctory '_db_backup'. I downloaded it and saved it in my pc. Then I create a new database. Again, I did not goto phpmyadmin, I click 'restore from backup' from thr hosting control centre. Everything seems alright.

I want to know if I backup and restore the database in this way, is there any difference with the former method? I just worried it will not be a proper way to do the migrate and there will be bugs in the new database.

Please give me some advice.

Thanks!
