Actual upgrade? I'm not sure what the expected output would have looked like.

Thanks for filing this issue, @jforman.

--reuse-values

By using this Helm option, the old, legacy, and incompatible values files are applied.
As per being incompatible, this might raise the error you're encountering.
Is there a specific reason for using this option?
As you already provide your customized value, it does not appear necessary to use it.

Hi @LeoColomb From the Netbox announcement post (https://netboxlabs.com/blog/netbox-helm-charts-5-0-available/) if you follow to "How do I upgrade", which points to https://github.com/netbox-community/netbox-chart/releases/tag/netbox-5.0.0#breaking-changes, it has the flag in the command line example under "Switch to the New Chart Repository".

I just did a test without --reuse-values and received a different error:

Thanks for your reply.
You're right regarding the upgrade guide.
That being said, in this guide, user custom values are not provided directly to the cli (no --values).
In any case, the second output is already some progress.
There are many ways to pass the Redis error, one of them being disabling then re-enabling redis. This should delete any previous Redis deployment. Redis databases are safe to delete.

I'm closing the issue as stale.
