How can i create a database replication between two databases using MySql?

Hello guys! Can anyone help with that? How can i create replication between two databases using MySql? Scenario: I have two databases A and B and i want the database A to update database B with time delay every 3-5 minutes. Also must notice that database A using Mysql v 4.0.17 and database B using Mysql 5.0 or higher. Is it possible to succeed  replication between them? Can anyone tell me the steps i need to follow? Thanks!!   

Hello dyereve,

and welcome to our small community.

About replication, you can't replicate different versions of mySql, and especcially 4 with 5 as there are major differences between those two.

Check the manual here :
