This bug/blueprint should cover the DB schema upgrade only. Additional work is required to handle the configuration changes and provide a complete migration tool.
Maru's patch to handle this was merged upstream a while ago. I added a link to the gerrit review. So the script will ship with the icehouse code.
Here is a wiki entry documenting the basic process for migrating from Icehouse-OVS-vxlan to Icehouse-ML2-OVS-vxlan. http://openstack.redhat.com/ML2_from_OVS It assumes an actually working OVS vxlan setup. :)

Ofer, The bug was fixed u/s and would be backported by jlibosva but according to jlibosva this patch only bans user from running it on havana. You can test the migration and report issues if you find any.
The migration works properly. From Havana: http://download.lab.bos.redhat.com/rel-eng/OpenStack/4.0/2014-07-15.2 To Icehouse : http://download.lab.bos.redhat.com/rel-eng/OpenStack/5.0-RHEL-6/2014-07-18.1 All-in-one + Compute node, GRE Please see all additional manual configuration that needs to be done after migration to ML2 https://bugzilla.redhat.com/show_bug.cgi?id=1121619
