Red Hat Enterprise Linux in-place upgrades

  • Article

Applies to: ✔️ Linux VMs

Caution

Following the process in this article will cause a disconnection between the data plane and the control plane of the virtual machine (VM). Azure capabilities such as Auto guest patching, Auto OS image upgrades, Hotpatching, and Azure Update Manager won't be available. To utilize these features, it's recommended to create a new VM using your preferred operating system instead of performing an in-place upgrade.

Note

Offerings of SQL Server on Red Hat Enterprise Linux don't support in-place upgrades on Azure.

Important

Take a snapshot of the image before you start the upgrade as a precaution.
