Specifications for Using Oracle Cloud Migrations
Review all specifications for using Oracle Cloud Migrations.
Licensing Requirements
Ensure that you comply with all the operating system (OS) and application licensing requirements when you run migrated instances on Oracle Cloud Infrastructure (OCI).
For information about licensing requirements of Microsoft products on OCI, see Microsoft Licensing on OCI.
Supported Migrations
The Oracle Cloud Migrations service supports the following source and target environments, and asset types:
Source Environment | Source Asset | Target Environment | Target Asset |
---|---|---|---|
VMware vSphere 6.5, 6.7, or 7.0 |
Virtual Machine |
Oracle Cloud Infrastructure |
Compute Instance |
Supported Source Environments
Oracle Cloud Migrations supports discovery of assets from the following external environments:
Source Environment | Discovery Mechanism | Discovered Assets |
---|---|---|
VMware vSphere 6.5 |
Remote Agent Appliance |
Virtual Machine |
VMware vSphere 6.7 |
Remote Agent Appliance |
Virtual Machine |
VMware vSphere 7.0.x |
Remote Agent Appliance |
Virtual Machine |
Required Virtual Machine Configurations
Following VMware virtual machine (VM) parameter values that you must set up before migrating the assets:
Parameter | Value | Setup steps |
---|---|---|
disk.EnableUUID |
True |
By default the If not, then follow the given steps to enable the parameter:
|
ctkEnabled |
True |
By default, Changed Block Tracking (CBT) is not enabled on VMware VMs. To enable CBT, see CBT on virtual machines. |
Supported Source VM Guest Operating Systems
The supported source VM Guest Operating System for Linux VMs and Windows VMs is mentioned in this section.
OCI ensures that workload instances that are migrated and launched according to the migration service guidelines are accessed using SSH.
For any operating systems version other than the ones covered by an official support service from Oracle (for example, Oracle Linux with Premier Support), OCI provides commercially reasonable support limited to getting an instance launched and accessible using SSH.
Although OCI supports launching an instance from a custom OS, OCI doesn't ensure that the OS vendor also supports the instance. If you're running Oracle Linux on OCI, you can automatically access Oracle Linux Premier Support.
OCI supports the following operating systems:
Windows VMs
Guest OS | Notes |
