Migrating MySQL 5.0 to MySQL 5.5

[Khuram Raza]

Greetings All,

can anyone guide me on how to migrate MySQL 5.0 to a new server running MySQL 5.5??

my server is running more than 95 databases, i need to migrate users along with it as they are also 200+ in number.

if i want to use MySQLDump, i can use this command

mysqldump -u root -pPassword -x --all-databases > db_dullll.sql
mysql -u root -pPassword < db_dullll.sql

but this is not working as databases get transfer users don't.

thanks in advance :)
