Migrate to Ampere on OCI with Heterogeneous Kubernetes Clusters - SitePoint
This post provides guidance on how to migrate a full stack cloud-native application from x86 instances to Ampere A1 instances on Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE).
The post focuses on migrating the MySQL database component of a LAMP stack application, using WordPress as an example.
The migration is done using an incremental approach, with almost no downtime, by creating an Arm64 node pool and adding MySQL replicas to run on these nodes.
