replication between different versions of mysql (3 replies)

I have a Sparc Solaris server running mysql v5.0.22 and an INNODB storage engine.

I do master - master (bidirectional) replication between another Sparc Solaris server also running 5.0.22.

If I upgrade one of the servers, say to version 5.1.57 or 5.5.19, can I do replication from my 5.0.22 server please.

Thank you
