Migrating to mysql cluster
I would like to know if there is a way to migrate smoovely between the 2 configurations i will describe bellow.
Currently the site runs on 3 dualxeon servers under a loadbalancer. each runs apache/php/mysql. The files are syncronized using rsync and the database using mysql replication. Php is 4.3 and mysql is Server: 4.0.21, Client: 3.23.52. Though the performance is ok i am not happy with mysql syncronization. I have to resync them quite often and i would like to move it to mysql cluster. For this we are planning to get 3 new servers on which we'll run the data nodes and management nodes ( each one will run them ). Now here is the question. Can the current mysql servers ( 4.0.21 ) act as sql nodes for the cluster? If not i will have to run them on the 3 new servers also. In this case, is it possible to have them use the 3.23.52 client libraries so that i wont have to recompile the php?
Thanks
