| 6 | * Migrate oauth_registered_consumer and oauth_accepted_consumer tables to a |
| 7 | * new database with minimal downtime. This script assumes relatively small tables |
| 8 | * (The WMF has <100 consumers and aout 1000 authorizations right now). |
| 9 | * |
| 10 | * To migrate to a new central wiki within your cluster, you roughly want to: |
| 11 | * 1. Set $wgMWOAuthReadOnly = true for all wikis in your running config |
| 12 | * 2. Move the oauth_registered_consumer and oauth_accepted_consumer tables with this script |
| 13 | * 3. Update the cluster config to point to the new central wiki |
| 14 | * 4. Set $wgMWOAuthReadOnly back to false, so users can manage their consumers as normal. |
| 15 | * 5. Migrate the OAuth logs using importCentralWikiLogs.php. |
| 16 | * 6. Done! |
