OCI Migration Hub
Whether you are looking to move a full data center, mission-critical workloads, or just a few applications, there are a variety of ways to migrate to the cloud, each with their own advantages and considerations. Oracle offers expertise and resources to guide you through the process to ensure a smooth and fast transition.
Accelerate cloud deployment and onboarding with Landing Zones
No matter what workload you are moving to OCI or the size of it, setting up your tenancy correctly from the start is crucial for a successful cloud deployment and smooth operations. Oracle provides landing zones that help you provision foundational services, such as compartments, network, security, policies, and logging, according to best practices and with minimal effort.
Migrate to the cloud as is
Certain workloads can be moved to the cloud without much change. While it’s not true for every scenario, often VMware images can be moved from an on-premises ESXi environment to VMware on OCI with minimal changes. This approach can be beneficial for workloads that are already stable and well established, as it minimizes the need for extensive testing and reduces the risk of introducing new bugs or issues. We identified three main categories for move as is:
Container to OCI Container Engine for Kubernetes
When moving containerized applications to OCI, it's possible to move them "as is" by running containers on Oracle Container Engine for Kubernetes (OKE). OKE is compatible with upstream Kubernetes typically supporting three recent versions. Common Kubernetes operators, such as External-DNS and cert-manager, support OKE. To use native services from OKE, such as OCI Load Balancers and Block Volumes, for persistent storage, annotation class names are typically required to be changed. Container images can be stored on OCI Container Registry which is compatible with Docker Registry. CI/CD jobs using a Docker-compatible registry and Docker CLI simply require updated credentials.
You can migrate containers manually or use one of the following tools:
- Migrate container registries to Oracle Container Infrastructure Registry (OCIR)
- Migrate with RackWare SWIFT to Oracle OKE Cloud
- Migrate OpenShift or Kubernetes workloads to OCI Container Engine for Kubernetes cloud using RackWare SWIFT
- Migrate workloads across on-premises and cloud with Commvault Metallic
- Automate Helm deployment to OKE with OCI DevOps pipeline

Physical to OCI Bare Metal
Physical servers can be migrated to OCI Bare Metal servers. OCI Bare Metal servers are dedicated physical machines that can be provisioned through the OCI console like OCI virtual machines. Physical machines can be migrated using third-party tools from the list below or you can do it manually by using tools, such as dd, to generate images of the disks and then using a tool, like qemu-img, to convert the disk images to OCI compatible images.
VMware to Oracle Cloud VMware Solution
When migrating VMware images to OCI, it's possible to move them "as-is" by simply uploading the image to the cloud and then running it on a VMware environment within OCI. This allows you to take advantage of the scalability and flexibility of the cloud while minimizing the need for extensive testing while reducing the risk of new bugs or issues.
Migrate to the cloud and replatform
Some see the move to cloud as a chance to modernize their applications. Modernizing an application can be as a simple as switching certain layers in the stack with managed services or as complex as advanced refactoring of monolithic applications to microservices. An example of a simple modernization is switching Oracle Database with Oracle Autonomous Database, minimizing management overhead, reducing human errors and associated risks. We identified three main categories for migrate and modernize:
VMware to Oracle Cloud Infrastructure (OCI) Compute
When migrating from an on-premises VMware environment to OCI, you can choose to replatform your applications to run on OCI Compute. Oracle Cloud Migrations brings an integrated migration experience with the ability to plan and manage virtual machines’ migration from on-premises environments and other clouds to OCI.
Physical servers and virtual machines to OCI virtual machines
When migrating physical servers or virtual machines to OCI virtual machines, you can use third-party tools from the list below or you can do it manually by using tools, such as dd, to generate images of the disks and then qemu-img to convert the disk images to OCI-compatible images. To benefit from the advantages of cloud services, consider replacing certain parts of your applications with fully managed services, such as Oracle Autonomous Database and MySQL HeatWave. This approach can lead to better performance, efficient architecture, and less management overhead in the long run.

Virtual machine to Container Engine for Kubernetes
When migrating from an on-premises virtual machine environment to OCI Container Engine for Kubernetes, you are required to containerize your workloads. Create a container image for each application, upload your images to OCI Container Registry, and build your application deployment definition using native Kubernetes format or a tool, such as Helm Charts. Provision OKE on OCI, and you are now ready to deploy your application. You can use OCI DevOps pipeline to automate CI/CD.
