Airflow 3 migration db clean

[r-magalhaes]

Hello,

I'm in the process of upgrading from Airflow 2.x to Airflow 3.1.5 and I've followed the Airflow 3 Migration documentation and it left me a question. On the step where it says we should run a airflow db clean before actually upgrading, is there any particular table that needs to be cleaned or is it supposed to be a full clean?

My question comes because if it's a full clean then I lose dag run data that I have to keep.

I run Airflow in a Kubernetes cluster and deploy it via Helm Chart.

Up to you. The clean recommendation is there in order to speed up the migration - you as Deployment Manager should choose how much of the old data is cleaned and which data you want to keep.
