The required steps to start the upgrade depend on the Windows Server version that you are upgrading to and whether your VM instance is based on a public operating system image or on an imported disk or image:. Run upgrade. The script completes the following steps:.
On the Select Image screen, select the configuration that matches your current configuration:. Depending on the machine type of your VM instance and your Windows Server configuration, the upgrade might take between 10 and 60 minutes to complete. During that time, you can observe the status through the serial port output :.
Wait until the machine has rebooted four times. Depending on the configuration of your VM instance, it might take 30 minutes or more for these reboots to occur. You can recognize a reboot by output that looks similar to this:. After the fourth reboot, wait until the output GCEMetadataScripts: Finished running startup scripts or No startup scripts to run appears.
You can now connect to the VM instance to verify that the upgrade has been successfully completed. Restart the VM instance to ensure all changes take effect. It might take 1 to 2 minutes for the reboot to complete before you can connect to the VM instance again.
Connect to the machine by using an RDP client. Use Windows Update to install the latest Windows updates. You might have to restart the VM instance multiple times during this process.
If you suspect that the upgrade failed or is not progressing, use the following approaches, in order, to diagnose the situation:. To check the progress of the upgrade process, view the serial port output of the VM instance:. During the upgrade, you should observe four reboots. If you don’t observe any progress for more than 30 minutes after the first reboot, it is likely that the upgrade failed. Go to VM instances. Using the EMS console, check the Windows Setup log files and the event log for indications that the upgrade is still progressing or for information about any errors that might have occurred.
When prompted for credentials, enter the username and password of an administrative user account. Use the remote PowerShell session to check the Windows Setup log files and the event log.
If you can’t connect to the instance by using Windows Remote Management WinRM , you can cancel the upgrade and analyze the log files from a different VM instance. To do this, follow these steps:. Stop the VM instance. Detach the boot disk from the instance. Create a new, temporary Windows Server instance, and attach the boot disk of the original instance as an additional disk. Use the temporary Windows Server instance to analyze the setup log and event log files of the instance that you were trying to upgrade.
After you have completed the analysis, detach the disk from the temporary instance and reattach it as a boot disk to the original VM instance. For information about troubleshooting your Windows Server instances, see Tips and troubleshooting for Windows instances. To avoid incurring further costs after you have completed this process, delete the installation disk. You can create an installation disk based on the Google-provided image at any time. If you don’t plan to upgrade more VM instances in the same zone, delete the installation disk:.
