Hi ytooyama-virtualtech,

your upgrade procedure seems right. Could you please check /var/log/maas/maas.log,
/var/log/maas/regiond.log and /var/log/maas/rackd.log for errors?

About the missing PCI and USB devices, MAAS needs to re-commission the machines to get that information. This action is not automatic, user action is required.

I will try again. and check the logs.

Thank you for your comment. I was mistaken.

I tried again, and I was able to upgrade without error. It might have been better to wait after the upgrade.
