Percona 5.5.62 master with Percona 5.5.22 slave

Are there likely to be any issues having a master running Percona 5.5.62 with a slave running Percona 5.5.22?

There are some resources that might help with this (they are not about your versions, but they have important/useful info). If after reading you have further questions, don’t hesitate to come back and ask. I am sure you’re already aware that 5.5 is getting pretty old now and don’t need me nudging on that! :slight_smile:

Just a nice general overview on running multiple versions of MySQL on the same server:

Take a look at those and see if they help any? There’s also a free (for an email address) recorded webinar on troubleshooting replication you might find useful
