Try Upgrades with ClusterControl
What if I need to modify a server’s configuration or take a node from a cluster offline? Will I get inundated with alerts?
No problem. Just set a Scheduled Maintenance period configurable for all nodes for that specific period. You’ll be presented with the following message: “All alarms and notifications from the cluster are disabled during maintenance mode.”
I’m still using MySQL 5.7, for example, and I need to deploy this version and not the latest. Is that ok?
Yes. We don’t provide all the older versions, but we do understand that it’s hard to be on the bleeding edge versions, so we’ll always offer a previous version too. And depending on the technology, you can see 4 or 5 different versions easily deployable.
