Upgrade ProxySQL¶

In an MySQL 8.4 or Percona Server for MySQL 8.4 environment, you may have the following issues:

ProxySQL contains counters that have not been updated to use the new terminology. Unexpected results may occur
The binlog reader errors out during initialization due to the use of the old terminology, such as SHOW MASTER STATUS command.

You can upgrade ProxySQL from version 1 to the latest version 2 or you can upgrade minor versions with ProxySQL 2.

Upgrade between major versionsUpgrade between minor ProxySQL 2 versions

Remove any ProxySQL 1.x.x packages before installing ProxySQL 2.x.x to upgrade ProxySQL.

Installing a later version automatically upgrades an earlier version ProxySQL 2.x.x.
