After discovering that in-place upgrade of Windows Hyper-V Server 2008 R2 to the 2012 version is not possible<\/a>, I set about the tedious task of exporting all the VMs from a Hyper-V Server box, installing Hyper-V Server 2012, and re-importing.<\/p>\n

There are many reasons to upgrade, not least the irritation of being unable to manage the VMs from Windows 8. Hyper-V Manager in Windows 8 only works with Windows 8\/Server 2012 VMs. It does seem to work the other way round: Hyper-V Manager in Windows 7 recognises the Server 2012 VMs successfully, though of course new features are not exposed.<\/p>\n

The export and import has worked smoothly. A couple of observations:<\/p>\n

1. Before exporting, it pays to set the MAC address of virtual network cards to static:<\/p>\n

\"image\"<\/a><\/p>\n

The advantage is that the operating system will recognise it as the same NIC after the import.<\/p>\n

2. Remove any snapshots before the export. In one case I had a machine with a snapshot and the import required me to delete the saved state. <\/p>\n

3. After installing Hyper-V 2012, don\u2019t forget to check the date, time and time zone and adjust if necessary. You can do this from the sconfig menu.<\/p>\n

4. The import dialog has a new option, called Restore:<\/p>\n

\"image\"<\/a><\/p>\n

What is the difference between Register and Restore? Do not bother pressing F1, it will not tell you. Instead, check Ben Armstrong\u2019s post here<\/a>. If you choose Register, the VM will be activated where it is; not what you want if you mistakenly ran Import against a VM exported to a portable drive, for example. Restore on the other hand presents options in a further step for you to move the files to another location.<\/p>\n

5. For some reason I got a remote procedure call failed message in Hyper-V Manager after importing a Linux VM, but then when I refreshed the console found that the import had succeeded.<\/p>\n

6. Don\u2019t forget to upgrade the integration services. Connect to the server using the Hyper-V Manager, then choose Insert Integration Services Setup Disk from the Action menu.<\/p>\n

\"image\"<\/a><\/p>\n

Cosmetically the new Hyper-V Server looks almost identical to the old: you log in and see two command prompts, one empty and one running the SConfig administration menu. <\/p>\n

Check the Hyper-V settings though and you see all the new settings, such as Enable Replication, Virtual SAN Manager, single-root IO virtualization (SR-IOV), extension support in a virtual switch, Live Migrations and Storage Migrations, and more. <\/p>\n","protected":false},"excerpt":{"rendered":"
