at the moment we have alomost 50GB database, that works on Mysql 5.1.52 (MyISAM). We have one master and one slave (binlog_format=MIXED).
Some times ago we have decided to migrate to the percona cluster, as we are tired of the instability and we are fed up with the complexity of the recovery of current solution.
so my question is
How we can easy migrate to percona cluster without downtime or with minimal downtime as much as possible?
Can you share your thoughts or recipes?
thanks in advance
sorry my english
