It is actually difficult to do what you have seen. The hardest part is
assigning permissions for a user. You can skip that if you are testing with

# mysqladmin create newdb
# mysql
mysql> GRANT ALL ON newdb.* to someuser at localhost IDENTIFIED BY 'somepass';
# mysqldump olddb | mysql newdb

That is it.
