Thanks a ton, I would have totally missed the block_device_mapping table (because on Folsom it lives on the nova db, not cinder's).</div><div class="gmail_default" style="font-family:verdana,sans-serif"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif">

I'm working on a company that has 2 openstack clouds, an essex installation and a folsom one. I'm trying to migrate a netApp volume from one to the other, checking the required fields in the database to copy the metadata. Obviously both volumes would be detached.</div>

Has somebody already tried it (and hopefully succeeded). It's really important for us in order to upgrade our openstack version, you'll understand it's impossible for us to do a "flip-the-switch" migration.</div>
