This process boots the virtual machine from the VHD upgrade file. The boot process backs up the server data, upgrades it to R12.0.x, and then restores the server data.
Before you begin
You must upgrade the server to IP OfficeR11.1.3.x.
After upgrading to IP OfficeR11.1.3.x, back up all the servers and services before upgrading to R12.0.x. See Creating an IP Office backup.
Procedure
Shut down the server using the following method:
Connect to the server's platform view/web control menus using port 7071.
Click Shutdown and click Yes. Wait approximately 90 seconds, after which on the connected monitor you will see services shutting down.
warning
Do not use any other method to shut down the server. Doing so will cause the loss of data and settings. This method creates files which the upgrade process uses.
In the Azure portal, click Virtual Machines.
Select the virtual machine and click Stop.
Use Switch OS from the VM Disks interface to set the R12.0 upgrade disk as the OS disk.
Set the original OS disk as a Data disk.
Select the virtual machine and click Start.
During the upgrade process, you can monitor the progress on screenshots displayed at Boot Diagnostics. The virtual machine is not accessible until the upgrade has finished.
When the virtual machine status shows as stopped, detach the upgrade OS disk.
Repeat the switch OS process to reset the original OS disk back to being the main OS disk.
Select the virtual machine and click Start.
Wait 10 minutes. During this time, the upgrade process will complete additional steps and reboot the server again.
When the server has restarted:
Check that the version shown is R12.0.x. If not, see Failure to upgrade.
Cancel any Consolidate Configuration Entries menu shown in IP Office Manager or IP Office Web Manager. The menu disappears after you have upgraded all IP Office servers in a network to R12.0.x.
Ignore any Upgrade Available prompts shown in IP Office Web Manager. You must only upgrade other IP Office servers using the processes in this document.
Following the upgrade, test and verify the operation of all services. If you find any issues, see Known upgrade issues.
You can reuse the upgrade image to upgrade multiple servers in sequence. However, you must only use an upgrade image to upgrade one server at a time.
When satisfied with the operation of the upgraded servers, you can delete the copies of the upgrade disk.
Only do this after when you are satisfied with the upgrade. The upgrade disk contains log files relating to the upgrade, see Upgrade logs. You need those log files to report upgrade issues.
