The link we used to migrate volume for before v0.6.2. https://longhorn.io/docs/0.8.1/deploy/upgrade/longhorn-manager/#migrate-pvs-and-pvcs-for-the-volumes-launched-in-v062-or-older
@akhfa The upgrade instruction was supposed to be executed before the upgrade, that might be the reason it failed. We will look into it.
@shuo-wu Can you check the upgrade steps still valid for v1.0.0? Since we’ve removed the compatible CSI driver in v1.0.0.
