@Ashna From the above logs, it's likely that you are trying to downgrade SigNoz using OtelCollector config of latest release.

If you are using older version, you should use older Chart version (or git checkout to release tag/branch) as well.
You are using older version of OtelCollector, while the configuration is pointed to the latest changes.

upgrade from 0.7.1 to 0.11.1

Prashant Shahi

11/02/2022, 12:52 PM
you would have to incrementally upgrade across the versions with breaking changes and run the migration scripts

Hi , I tried to upgrade to 0.8.0 from 0.7.2 and changed to these below values Alertmanager 0.23.0-0.1, OtelCollector 0.43.0-0.1
Still I am getting the same error

The Helm chart and the OtelCollector configuration you are using is for v0.11.x while you are using SigNoz version v0.9.x
you would have to incrementally point to specific chart versions with signoz versions and run the migration scripts.
It would be much easier to clean up existing signoz cluster and install latest one.

Okay
But how will I get the old data?

Prashant Shahi

old data can only be retained if you follow the step-by-step upgradation and run migration script

I don't think you are pointing
helm
to correct chart versions.
Run the following to get list of various chart versions and note the signoz version next to it.
Copy code
helm search repo signoz --versions
you will need to pass
--version
flag to set specific chart version for each breaking change release for your
helm upgrade
commands.

Hi,
We are deploying using docker
p

Prashant Shahi

11/04/2022, 2:55 AM
Oh, I see. That means you would have to
git checkout
to release branch or tag of each breaking changes incrementally and also run the migration scripts.

Hi
While tring to migrate as per the above docs, getting the below error
Error: unknown flag: --mem-ballast-size-mib 2022/11/11 081456 collector server run finished with error: unknown flag: --mem-ballast-size-mib

Prashant Shahi

That flag was removed long back.
I don't think you are migrating properly
You would have to checkout to
v0.8.0
:
Copy code
git checkout v0.8.0
And follow the migration guide here: https://signoz.io/docs/operate/migration/upgrade-0.8.0/ Similarly, you would have to checkout to: •
0.8.1
and follow migration scrips here: https://signoz.io/docs/operate/migration/upgrade-0.8.1/
0.9.0
and follow migration scrips here: https://signoz.io/docs/operate/migration/upgrade-0.9/
0.10.0
and follow migration scrips here: https://signoz.io/docs/operate/migration/upgrade-0.10/

can you please make sure that you do not have any local changes in the otel-collector config or docker-compose YAML?
