For the duration of the switchover (1 month), deployers are kindly requested to refrain from large db schema changes and avoid deploying any kind of new feature that requires creation of tables. There will be a train freeze in the week of Sept 10th and Oct 8th.
The net effect of the switchover and switchback for volunteers is expected to be some minutes of inability to save an edit. For readers, everything will be as usual.
