Here is what to do if you use Hyper-V RC0 or RC1 and want to update to Hyper-V RTM. I did this recently with my server.

1. Apply the snapshot you want to take with you to RTM
2. Start the virtual machine with this snapshot applied
3. Shutdown your virtual machine
4. Delete all Snapshots
5. Wait for the merge to complete
6. Uninstall the Hyper-V role with the Server Manager
7. Logon to the server
8. Wait for the Configuration Wizard to complete (it starts automatically)
9. Apply the update details.aspx-FamilyId=F3AB3D4B-63C8-4424-A738-BADED34D24ED&displaylang=en
10. Restart the server
11. Logon to the server
12. Add the Hyper-V role with the Server Manager
13. Restart the server
14. Wait for the Configuration Wizard to complete (it starts automatically)
15. Your virtual machines should be there after the update
16. Reconnect your virtual machines to the virtual network
17. Start your virtual machines
18. Insert the Integration Services Setup Disk and update the Integration Services
19. Restart the virtual machine

Done.

By the way: I did not need to reactivate my virtual machines.
