Upgrade to v0.8.1 from earlier versions

SigNoz v0.8.1 requires users to run migration script for dashboard.

If you had created dashboard in v0.8.0 and before, you would need to run this script to sanitise dashboard data.

First Upgrade to v0.8.1

Follow the platform specific instructions to upgrade to 0.8.1 and above.

After upgrading to 0.8.1, it is recommended to run the migration script before modifying any existing dashboards. It could potentially cause irreversible changes to dashboard data.

Steps to run migration script

For Docker

cd to SigNoz repository and run following commands:

cd deploy/docker/clickhouse-setup
 
docker run -it -v $PWD/data/signoz/:/var/lib/signoz/ signoz/migrate-dashboard:0.8.1

Output should be similar as below:

tar xzvf migrate-dashboard-v0.8.1-linux-amd64.tar.gz

To copy the binary in persistent volume path /var/lib/signoz in query-service:

kubectl cp -n platform ./migrate-dashboard my-release-signoz-query-service-0:/var/lib/signoz/migrate-dashboard

To exec into the query-service container:

kubectl -n platform exec -it pod/my-release-signoz-query-service-0 -- sh

Now, change directory to the /var/lib/signoz and run the migration script:
