No action is required. However, if you decide to **downgrade** for any reason and **disable RBAC**, you'll need to run through the following guide before upgrading again. The aforementioned sequence of actions (upgrade, downgrade, disable RBAC, upgrade again) causes legacy access control and role-based access control systems to be out of sync. As a side effect, permissions for some Grafana resources, like dashboards, might be lost. To prevent that from happening, before you upgrade Grafana back again, please take the following steps: 1. Stop Grafana. 2. In your database, run the following SQL queries: ```sql DELETE FROM builtin_role where role_id IN (SELECT id FROM role WHERE name LIKE 'managed:%'); DELETE FROM team_role where role_id IN (SELECT id FROM role WHERE name LIKE 'managed:%'); DELETE FROM user_role where role_id IN (SELECT id FROM role WHERE name LIKE 'managed:%'); DELETE FROM permission where role_id IN (SELECT id FROM role WHERE name LIKE 'managed:%'); DELETE FROM role WHERE name LIKE 'managed:%'; DELETE FROM migration_log WHERE migration_id IN ('teams permissions migration', 'dashboard permissions', 'dashboard permissions uid scopes', 'data source permissions', 'data source uid permissions', 'managed permissions migration', 'managed folder permissions alert actions repeated migration', 'managed permissions migration enterprise'); ``` 3. Start Grafana again. ### Case-insensitive usernames and email addresses Usernames and email addresses are now treated as case-insensitive in Grafana. If you're not using MySQL as a database, potential user identity conflicts may arise when users try to log in. We recommend you resolve any potential conflicts in advance by using the [Grafana CLI tool for managing user conflicts](/blog/2022/12/12/guide-to-using-the-new-grafana-cli-user-identity-conflict-tool-in-grafana-9.3/). ### Dashboard previews removal We've removed the Dashboard previews feature introduced behind a feature flag in Grafana version 9.0. No action is required. The `dashboardPreviews` feature flag is no longer available and can be safely removed from the Grafana server configuration.
