Upgrading a single CUCN server to 8.6.1 without any downtime

Does anybody have any recommendation for me to upgrade a single CUCN server running 7..0.2 to 8.6.2a ?  Eventually I am going to run on virtualized servers.  Is there a best practice for this without any downtime?  I am thinking of building new virtualized and implementing the COBRA backup and restore but will this work?  Has anybody tried it?  I dont have a way of trying it.
