Upgrading VMware Software
Learn how to upgrade the software running on your SDDC and ESXi hosts.
When a new version of the VMware software becomes available, VMware Solution notifies you and provides a workflow that guides you through the upgrade process step-by-step.
There are significant architectural changes to the platform from vSphere version 6.x to 7.x. To perform the upgrade, the workflow provisions a new vSphere 7.0 SDDC and ESXi hosts on OCI VMware Solution and uses VMware HCX to migrate workloads to the new vSphere 7 SDDC. During the upgrade workflow two more VLANs are required for provisioning and migration. You can create the VLANs before you start the workflow, or let the workflow create them for you.
The upgrade workflow creates new, upgraded ESXi hosts to replace the old hosts. The new hosts use the hourly billing rate and begin billing as soon as they're active. The workflow requires you to delete the old hosts after you verify that the new hosts are functioning correctly. After the old host is deleted, the new host is updated to use the billing interval of the old host. Be sure to delete old hosts in a timely manner to avoid unnecessary charges. See Transferring Billing Commitments for more information.
OCI only supports an in-place upgrade workflow from version 6.x to 7.x. To upgrade from 7.x to 8.x, create a new SDDC and hosts using version 8.x. Then, migrate workloads from the 7.x SDDC to the 8.x SDDC, and transfer the host billing commitments. See Transferring Billing Commitments for more information.
Using the Console
Optionally, create two additional VLANs that the workflow can use for provisioning and migration. For more information, see VLANs.
