Comment 3 Nir Yechiel 2014-02-19 09:28:32 UTC

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.

Comment 8 Terry Wilson 2014-04-08 17:05:31 UTC

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.

Comment 11 Terry Wilson 2014-05-02 22:20:47 UTC

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. :)

Comment 16 lpeer 2014-06-12 12:58:09 UTC

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.

Comment 25 Toni Freger 2014-07-23 07:09:38 UTC

The migration works properly.

From Havana:

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
