I’ve currenlty got two MySQL 5.0.67 server running circular replication. We have added a 3rd server running Percona 5.5 currently as a read only slave for testing solid state hard drive performance.
for the next step I’d like to put the Percona system into a 3 way circular replication but am not sure if there will be any issues with replication between the different versions.
Anyone have any experience with this?
Since the actual write queries won’t change the only thing I can thing of that would effect things is if the 5.0 db’s can’t read the binary logs on the 5.5 db
