Guide to using the new Grafana CLI user identity conflict tool in Grafana 9.3

Grafana 9.3 introduces a new command in the Grafana CLI designed to address user identity conflicts caused by case-sensitive logins and emails, which can result in multiple accounts for the same user and related complications. This tool allows administrators to manage these conflicts by listing conflicting user accounts, generating a conflict file for review, validating changes, and ingesting the resolved file to update the database, with the last step being irreversible. The tool helps streamline user management by resolving discrepancies and preventing the creation of "zombie" accounts or split user permissions. While this feature supports ongoing efforts to enhance Grafana's consistency, it will be phased out by October 2024, encouraging admins to utilize it for versions up to Grafana 11.4. For those running Grafana Cloud or using MySQL, these conflicts are not encountered, and further configuration settings can ensure future conflicts are avoided.
