# Maintenance

- [Improving performance](/sonarqube-server/server-update-and-maintenance/maintenance/improving-performance.md): Improve the performance of your SonarQube Server instance by increasing the number of Compute Engine workers, parallel analysis processing, and optimizing the analyzers' loading.
- [Migrating database](/sonarqube-server/server-update-and-maintenance/maintenance/sonarqube-db-copy-tool.md): The SonarQube database copy tool helps you migrate your SonarQube Server database between vendors.
- [Backup and restore](/sonarqube-server/server-update-and-maintenance/maintenance/backup-and-restore.md): Backing up and restoring your data.
- [Reindexing](/sonarqube-server/server-update-and-maintenance/maintenance/reindexing.md): Starting SonarQube Server after an update or a restore from a backup triggers a rebuild of the Elasticsearch indexes. You can also force a reindex.
- [Deprecations](/sonarqube-server/server-update-and-maintenance/maintenance/deprecations.md): Deprecation policy and API deprecations.
- [Deprecation policy](/sonarqube-server/server-update-and-maintenance/maintenance/deprecations/deprecation-policy.md): The goal of the deprecation policy is to ensure that users are aware of what is changing and have time to adjust before a feature or an API component is dropped on a planned date.
- [Monitoring API deprecation](/sonarqube-server/server-update-and-maintenance/maintenance/deprecations/monitoring-api-deprecation.md): Monitoring deprecated Web API components is an important part of checking that your SonarQube instance is using deprecated endpoints.
