#C01HWQ1R0BC @Nagesh Bansal Hi Team I am planning to upgrade our SigNoz deployment to the latest version with helm chart. Before that, I want to take a backup of the existing 
signoz.db
(SQLite database) and use it to restore data (users, dashboards, alerts, etc.) after reinstalling the latest SigNoz version. My plan is: 1. Take a backup of the 
signoz.db
file from the current 
query-service
pod. 2. Uninstall the existing SigNoz Helm release. 3. Install the latest SigNoz Helm chart. 4. Use an initContainer or another mechanism to copy the backed-up 
signoz.db
 into the new 
signoz
pod (replacing the default DB). Can you please confirm if this approach is supported in our setup?

Can you exec into the signoz container and run:

apk add sqlite
sqlite3 /var/lib/signoz/signoz.db
> SELECT * FROM migration
