This script automates the process of upgrading Ubuntu VMs in Azure to Ubuntu Pro. It finds VMs with a specific tag, updates the license type, installs the Ubuntu Pro client, and activates it with auto-attach.

• Finds VMs in a resource group with a specific tag (default: toupgrade=true)
• Verifies VM is running before attempting upgrade
• Verifies VM is using a Canonical image
• Updates the VM license type to Ubuntu Pro
• Installs and activates Ubuntu Pro on the VM
• Removes the original tag and adds a new tag after successful upgrade (default: upgraded=true)
• Provides a detailed summary of processed and skipped VMs

./upgrade-script.sh rg=ResourceGroupName [tag=TagName] [value=TagValue] [tagafter=UpgradeTagName] [valueafter=UpgradeTagValue]

• rg: (Required) The Azure resource group containing the VMs
