What to consider before you upgrade

Upgrading from the Release Candidate to the release version

• Saved state files are not supported between the Release Candidate (RC) and the release version of Hyper-V. All virtual machines should be shut down correctly before you install the release version of Hyper-V.

Note If you have already applied the release version of Hyper-V, virtual machines in a saved state will not start. Additionally, you will receive the following error message:

An attempt to initialize the virtual machine saved state failed.

To resolve this issue, select the Delete Save State option for each virtual machine that is currently in a saved state.

• Snapshot files are not supported between the Release Candidate (RC) and release version of Hyper-V. All virtual machine snapshots should be deleted by using the Delete Snapshot Subtree option for each virtual machine.

Note After you delete the snapshots and after you shut down the virtual machines, the changes that exist in the snapshot files (.avhd files) will merge into the parent virtual hard disk file (.vhd).

This operation can take a while. To verify that the snapshots have merged into the parent virtual hard disk file, locate the snapshots, and then verify that no .avhd files exist.

Note The saved state and snapshot files are compatible if you are upgrading from Release Candidate 1 (RC1) to the release version of Hyper-V.

Upgrading from a prerelease version (beta version) of Hyper-V to the release version of Hyper-V

If you run virtual machines on a Hyper-V prerelease build, follow the steps that are described in the following Microsoft Knowledge Base article after you upgrade to the release version of Hyper-V:
