Recent change https:/

(11:48:31 AM) mgoddard: mriedem: is it possible to run ODM for a cell DB before other cells have been upgraded? /docs.openstack .org/nova/ latest/ user/cells. html#faqs
(11:49:10 AM) mriedem: possible? sure
(11:49:11 AM) mgoddard: just wondering about the upgrade one cell at a time scenario, should I include the data migrations as part of that cell's upgrade, or all together at the end?
(11:49:20 AM) mgoddard: advisable?
(11:49:50 AM) mriedem: i'm not sure
(11:49:52 AM) mriedem: dansmith: ^?
(11:50:07 AM) mriedem: i would think it's ok to do it per cell upgrade
(11:50:15 AM) dansmith: mriedem: mgoddard at the end
(11:50:27 AM) mgoddard: dansmith: ack, thanks
(11:50:47 AM) dansmith: mriedem: do you mean target the cell and do data migrations just within that cell?
(11:50:56 AM) mriedem: i think that's the question yeah
(11:51:14 AM) dansmith: I mean, I guess that's okay, but since they don't need to be run until later, I would just do them later I guess,
(11:51:22 AM) dansmith: and if the api is all upgraded first then those migrations would be fine
(11:51:33 AM) dansmith: so I guess either way, but I'd just do it later personally
(11:51:37 AM) dansmith: mgoddard: ^
(11:51:50 AM) mriedem: mayhap we should be capturing some of this in the faqs https:/
