Upgrade to 0.8.0 from earlier versions

v0.8.0 is a breaking release which requires data migration, if you are upgrading from an older version then you have to run the data migration scripts to be able to see past data.

First upgrade to 0.8.0

Follow the platform specific instructions to upgrade to 0.8.0 and above.

Note that the past data will not be visible on the new application until you run the migration script.

• git clone -b main https://github.com/SigNoz/signoz.git && cd signoz/deploy/
• git checkout v0.8.0
• ./install.sh

Kubernetes

• helm repo update
• helm search repo signoz --versions
• helm -n platform upgrade my-release signoz/signoz

Steps to run migration script:

  -it -d signoz/migrate:0.8 -host=clickhouse -port=9000
