Over the next 5 weeks we will be upgrading our Mysql nodes to newer hardware and an updated Operating system. We plan to migrate two nodes every morning between 07:00 and 08:00 AM and downtime per node is expected to be 20-30 minutes appx. We have thoroughly tested the process and have migrated a number of nodes over the past two weeks without issue however downtime will be dependent on the number and size of databases on each node.
