Choosing ProxySQL Versions

Upgrading MySQL major versions in production is never just a version bump - it’s a carefully planned process involving compatibility checks, replication strategy, testing, and controlled cut-over.In this episode, we walk through a practical MySQL Major Version Upgrade Checklist based on real-world DBA workflows. We are covering MySQL replication as base setup for upgrade. It is possible having other approaches though this is one of the time tested. From testing to final cutover and rollback planning, this podcast covers the essential steps needed for a safe and zero-downtime upgrade.Who this is forMySQL DBAsDBA ManagersAnyone working with MySQL or hosting MySQL in their environment🔔 Subscribe for more MySQL tips and deep dives!📖 Blog: https://kedar.nitty-witty.com/blog/💬 Got questions?
