I have a dedicated server running MySQL 5.7, installed using MySQL's Yum repository.
Yum always installs the latest version, which is MySQL 5.7.11 at the time of this writing.
I want to replicate this server to Amazon RDS, to have an offsite, real-time backup.
The problem is, RDS is always at least one minor version behind. To illustrate this, they just released MySQL 5.7 on RDS yesterday, yet they did not pick the latest version, and only offer MySQL 5.7.10.
So I would be replicating from a newer master to an older slave.
Is this acceptable, as long as we're talking minor versions?
The only page I could find on the MySQL website is this one: https://dev.mysql.com/doc/refman/5.0/en/replication-compatibility.html
It basically says that you can only replicate from an older master to a newer slave, but they are talking major releases, i.e. 5.6 to 5.7.
This does not give me a clue to whether it is OK to replicate to a slave running an older minor version, e.g. from a 5.6.11 master to a 5.6.10 slave.
