Upgrading Hyper-V Virtual Machine to R11.1 FP1

Scroll Prev Up Next More

This process boots the virtual machine from the VHD upgrade file. The boot process backups the data on the server's existing drive, upgrades its components to R11.1 SP2 and then restores the server data.


1.Upgrade the server to R11.0.4.5 using the standard ISO upgrade process. Test and verify correct operation of all services on R11.0.4.5 before upgrading to R11.1 SP2/FP1.

It is especially important to verify Media Manager is running if the server has stored call recordings. Media Manager must be running during the upgrade process for correct migration to R11.1 SP2/FP1.

2.Ensure that you have a full backup in order to be able to recover from any upgrade issues. See Creating a Back Up.

3.Download the Hyper-V upgrade VHD file.


1.Shutdown the server using the System | Shutdown in its port 7071 web control menus:

! Warning: Do not use any other method to shutdown the server. Doing so will lead to the loss of data and settings. This method creates backup files for some services that are then used for the upgrade.

a.Connect to the server's web control menus using port :7071.

b.On the System menu, click Shutdown and click Yes. Wait approximately 90 seconds after which you should see the services shutting down.

2.Copy the VHD file to the folder on the Hyper-V platform used to store the virtual disks.

3.In Hyper-V Manager, right-click on the virtual machine and select Connect to display a console window.

4.Click the hyperv_connect_stop_icon icon to stop the virtual machine.

5.Select File | Settings.

6.If the virtual machine has an additional virtual disk for Media Manager, click on that drive and change it to IDE Controller 1, Location 0. Click Apply.

7.Select the existing main hard disk and change it to IDE Controller 0, Location 1. Click Apply.

8.Click IDE Controller 0 again.  

a.Select Hard Drive and click Add.

b.Check that the Controller is set to IDE Controller 0, Location 0.  

c.In the Virtual hard disk field, browse for the upgrade VHD file and click Open. Click Apply.

d.Click OK.

9.Restart the virtual machine by clicking the hyperv_connect_start_icon icon. The virtual machine is rebooted from the upgrade VHD file which starts the process of upgrading the other virtual drives to R11.1 FP1. When completed, the server is automatically powered off.

10.Reset the virtual drives back to their original boot order:

a.Click on the upgrade VHD file and click Remove. Click Apply.

b.In the settings of the previous main drive, set the Location of the drive back to IDE Controller 0, Location 0. Click Apply.

c.If a Media Manager drive is also present, set it back to IDE Controller 0, Location 1. Click Apply.

d.Click OK.

11.Restart the virtual machine by clicking the hyperv_connect_start_icon icon. Once the server has restarted:

a.Check the version of the server is now shown as R11.1 SP2. If not, see Failed to Upgrade.

b.Check the operation of the services (calls, voicemail, one-X Portal for IP Office, etc). See Known Upgrade Issues for a number of known issues that affect some upgrades.

c.If part of a network, continue with the next server. See Upgrading a Network of Servers.
