Hi,

Can someone please explain to me what the command nova-manage db migrate_flavor_data exactly does? We are having trouble upgrading our openstack environment from kilo to liberty or mitaka.

We are getting the error: stdout: error: There are still 90 unmigrated flavor records. Migration cannot continue until all instance flavor records have been migrated to the new format. Please run ' nova-manage db migrate_flavor_data' first.

When i run this command it fix 6 instances: 6 instances matched query, 6 completed i still got 84 records left needs to be fixt otherwise the upgrade keeps failing. Can somebody help?

Thank you in advanced. Kind regards,

Egv
