In the session, I will be discussing in-place upgrades for VMs running Windows Server in Azure. This process allows for the upgrading of the operating system of a virtual machine to a newer version while keeping all applications, data, and settings intact. I will cover the prerequisites for in-place upgrades, including the compatibility of the operating systems and the available disk space. During the session, I will discuss best practices for in-place upgrades, including taking backups, testing the upgrade in a non-production environment, and monitoring the upgrade process. Finally, I will discuss post-upgrade tasks.
